Kia SURGING Idle? ('97 Sportage 4x4) 

Car owner here. A little back story on this one. As Ivan mentioned in the first video, this car belonged to my neighbor. It had not been on the road in over 3 years. She approached me to try to get it running and inspected. After getting it fired up I noticed paperwork where they attempted to inspect the car back in 2017. It had a tremendous number of trouble codes. The neighbor decided it wasn't worth the time and trouble and offered me the car. While not an expert, I'm a DIY mechanic. Having learned from Ivan (and Eric O) that there would be a common theme to all of the trouble codes, I pulled a wiring diagram and went to work. I found an engine wiring connector in the back of the engine (a real pisser to get to), and when I opened the connector there was a large amount of corrosion. I did my best to clean it up given the tight space I was working. After plugging it back in, all of those trouble codes went away and the car ran great. At least for a little while. After trying to get it inspected, it lost communication at the DLC. Dash lights would not work etc. Every connector I unplugged had green puss. The car needed a new harness, but it wouldn't be cost effective even if you could find one. After the most frustrating experience working on a car, I finally made the decision to call in an expert. Living in Delaware, I made the 3 hour trip to State College to see Ivan. I towed the Kia on a U-haul trailer over the mountains of PA. Needless to say, Ivan's attention to detail and problem solving skills made the trip 100% worthwhile. Fast forward to today. I gave the car to a family member who absolutely loves it. I did have to replace the TPS pigtail that was causing problems, but so far so good. The truck is rust free and very heavy duty underneath. They don't build KIAs like this anymore. PHAD saves another one. Rob

“That chineese air flow meter is reporting accurately “. Lol

Yet another lesson in not firing the parts canon, especially when the canon is loaded with unbranded eBay crap.

Unshooting the parts canon fixed it. Thanks for bringing us along, Ivan!

Nice to see and older vehicle run so well! Good work!

Great job Ivan and the best part NPR !! Awesome !

OEM, the most important lesson here…..

I always learn something from Ivan . Thanks

Can you believe there was a Kia Sportage backed by Kia that raced at Baja and Dakar back in the 90s🤯 so cool

I like "get the little truck run 100% correct!" Great job Ivan! Thanks for Sharing!

A happy customer. You helped that guy to keep his 23+ year old car on the road. Ivan you are a kind if good Samaritan!

A good outcome Ivan. Just goes to show Eric is correct, NEW does not always mean good. It does mean Never Ever Worked! The original OEM one was clearly better than the new one. I can.t recall if the new one was OEM or not. I am going with Not.

Great diagnosis and fix Ivan! Take away from this is that comms and PID's for older vehicles are limited and that knowledge on how things work and taking a logical approach will get results. I'm quite sure if you put back most of the old components that they'll most likely still function. Thanks for walking us through. Cheers!

When you mentioned surging idle, I was expecting the old Toyota or Ford old idle surge when low on coolant. Being an older vehicle, but that was a quick surge, not the old school upppppppp then downnnnn. Great work as always and NPR!

Great content Ivan, you saved another.

Great video, new parts does not always mean a better part!

Yea! It Passed. Awesome Ivan!

That’s a great example of how the parts cannon makes things worse! Great video.

Good vid man. An actual informative content.

Those were neat body on frame little trucks. It was Kia before it became part of Hyundai and if I remember correctly, it had a Mazda engine in it.

Nice work Ivan 👍🏼

Good for you for not rushing to the throttle stop.

Ivan, Great video set and fix - thank you! Paul (in MA)

Great follow up video, oem it's always better. Good troubleshooting skills, truck is back in the road. Take care Thanks 😊

Nice job Ivan

Great job Ivan! In my long career of electronics, I have found about 95% of malfunctions are mechanical. Most were corrosion, poor contacts, cracked solder joints, or stressed broken wires. The 5% electrical failure usually was caused by the mechanical side shorting, or over current the circuits to the point of failure. The Art of Diagnosing is determining whether its the Cause or the Effect.

Never knew a screwed TPS could cause an idle like this, Thanks a bunch.

Love the fix. Sometimes old school methods work best.

Always a great job

Sometimes new don't always mean better🤣🤣🤣. New cheap parts can send you through a tailspin, but you can't fool the experts! Great job Ivan!

The owner brought it to the right place. We don’t have those inspections here in Michigan anymore, lots of cars running like crap for no good reason! Although you don’t see a lot of cars older than ten years because they rust to dust by then!!

Would have been interesting to see a reverse parts cannon. Install all the old parts and see what was unnecessary 🙂

Sweet diag. Thanks Ivan!

Fantastic . Basic common sense diagnosis. Loved those little Kias but where I live the rear frames just rot away.

Nice one Ivan👍 Gotta love the customers with self inflicted cheap parts cannon/tinkering issues🤣🇦🇺

Great video.

Love the content!!!

great job Ivan I wish you were closer

Ivan, you just proved my point! Always stick with OEM!! I've been telling people to stay with oem! You reversed parts cannon! That's neat trick! Ha! I have a slight surging idle on my ex wife's car, but i will check the tps and see what the maf is reporting and the position of the tps. I'm sure i got some autozone or napa crap in there. I need oem!! Lol. Do a widdle test too. That's cool feedback from Rob on the video and his comment! It shows your character and dedication to attention to detail. That's why i enjoy watching you do mind blowing cool case studies and your diagnosis thinking! Great job, Ivan!

Thanks for part 2. I'm sure customer is very happy.

Hang on to those remaining oem parts.

great video . that slow refresh rate would make many people throw in the towel lol

Is there anything you cant do??? Lol! Awesome Ivan!

Good job

I had the same type of problem on a Buick century one time, turned out someone tried removing the connector on the throttle position sensor and had broke the plug in on it. After it was fixed it ran fine where as before it would surge and shift hard when you first took off. Crazy how much difference it made with a bad connection.

Молодец иван

Fundamentals for the win! The manufacturer doesn't give us a procedure, so we'll use our knowledge instead.

I have a 2010 Kia forte when I start it will idle at about 1500rpm. When I put it into gear it will kick down to 1000. It runs lower on reverse than drive but highest in Park. Sometimes when I'm driving it it will have a slight surge. not every time just once in awhile and it's just maybe about 500 RPMs up and then back down over and over again. Just enough to notice it's happening. There are other times when I start the car that it actually feels like it wants to stall and if I press on the gas while it's still in park when it's feeling like it wants to stall after starting it that will usually fix the issue. It'll just go back to being at the high RPM again. One time while driving it it went up to 3&4 rpm wouldn't come out of that I just got it around the block back home and parked it thinking it was done for I waited a few minutes restarted it and it was back to its normal and driveable again. I feel like nobody can tell me what's wrong with it but clearly something is

Cool! 👍

11:50 I was wondering if that vacuum line to the trans was still not doing anything (effectively seeing WOT), but then you noticed you had the selector in "2" not "D".

The vehicle emissions test has been disbanded in Ontario Canada since April 2019 .

Thank you Ivan for this video. Do you have plans to migrate to Pico 7 in the near future?

Customer should have a really good car now.Even if customer had replaced evrything with OEM parts this would not have rectified the problems.Just shows that even if your first investigation is not conclusive another look at suspect wiring/parts can pay off. 2 good video's on this Kia Thank you

My VW had a intermittent compressor malfunction - not cycling. It took 4 years to finally find the wire that had the incomplete break in it. what a hassle.

Boom!!

KIA -Killed In Action- Keeping It Alive Never deem parts as bad until confirmed they are Another step by step approach repair saves another from the boneyard The owner mentioned Pa Mountains. Lucky he didn`t come up via route 125 , white knuckles and clenched cheeks style all the way with that road Haha

Hello Ivan. I'm trying to locate the EGR valve on my '98 Sportage (failed smog NOx), but it's not on the lower front of the intake manifold like shown on this '97 at 1:51 of the video. Oddly enough, it looks like that area on the '98 manifold has been sealed up. After looking through my factory repair manual, I came across a couple of images that appear to show that the EGR valve was moved to the lower back area of the intake manifold close to the firewall. It's just a random (not a photo) image and doesn't have it labeled as the EGR, but it definitely looks like it. My manual references the EGR a couple times but never actually says anything about where it's located. I'm just wondering if you had any information to confirm that this is the location on the '98 because I can't actually see that area without taking a bunch of parts off the vehicle. Sorry for the long comment, just hoping for some help before I start dismantling this thing only to find it's not in that location.

Yes! I'm addicted to these diag. videos. I have a strange one at work right now. Chevy Express 6.0L but runs on CNG. Bank one -30% long term and bank two 30%. B1S1 0.9mv B2S1 0.0mv. Injector duty cycle bank one 5.1msec and bank two 16msec.

When i worked for kia they had problems in TPS sensors that would not set a code yet cause a rolling idle. Also carbon build up in the throttle plates.

👍👍

I have a 4x4 sportage in 2001, please tell me the order and color of the ISC socket cabble, because I lost track and all three were cut off at the socket head, please reply 🙏🏻🙏🏻 thank you..

That is one lucky guy. Do some maintenance and it will probably give him 50 to 100k miles easily.

What is the update on the new garage ?

what is that sign reflecting on the scanner around the 7:38 mark, it seems to be in Russian wondering if anyone knew...

Interesting that all that was wrong was a buncha bad connections. We have all this wonderful technology in this world but still have so many connector issues. I repair appliances and instead of making better and beafier connectors there are almost microscopic now go figure. Just had to order a lady a control because the1/4 terminal they used is in a plastic housing and for some reason it doesnt make good enough contact and causes wire to burn off control. Never used to use plastic around the connector and seen a lot less issues. Still trying to figure out how to move electrons with no wires maybe someday i suppose lol.

Hola, tengo una Kia Sportage igual a esta incluso el color, es del año 1995, 2.0 mazda, motor a gasolina, con 134.000 km originales. Y tengo problema con el ralentí, el cableado es el original y la tps es bosch made in Germany pero la idle es distinta, es de cortina, y esta puesta al frente. La camioneta se aceleraba sola al ir conduciendo y subia a unas 2000 rpm. Me bajaba la golpeaba con un martillo y se acomodaba a sus 800 rpm original porque estaba sucia. Compré una nueva y ahora mientras conduzco en ciudad las rpm a veces suben y bajan un poco. Yo solo desenchufe la vieja idle y conecte la nueva. Aquí nadie sabe repararla. Estoy en Argentina. Algun consejo? Será que hay que reiniciar algo en la computadora? Será el tps? Lmpiar el conector de la tps con un limpia contacto servirá? Muchas gracias. Felicitaciones y cordiales saludos!

What will the neighbor say now that had it ?

cool

Berapa % nilai sensor TPS saat kondisi mesin idel

Pine Auto Hollow Diagnostics.

Give her the beans

So questionable parts and pin fitment, great job

What was the manufacturers specific code p1505? Was that a idle issue from all data information I missed something there somewhere.

I saw that flag. :D

Always found the pedal configuration awkward. There is a footrest by the Gas pedal and you always press on that instead of the gas.

Npr no parts reqired

I would have cleaned the throttleplate as well.

Always use OEM electric parts and never use eBay special

Saving this car from the crusher vs buying a stupid new Tesla is way better for the environment and the customer’s wallet. 👍🏻

You know, Ivan... being of Russian heritage and having a Trump poster in your garage your gonna get Trump in trouble! HaHa

I guess even the older port injected Korean cars sound like a garbage truck.
