Thanks for the video! Did this on my 1990 Corolla and it did not look too dirty, but it made a huge difference! Driving better than when I bought the car (132,000 miles now, I bought it 9 yrs ago at 88,900 miles- only major repair so far is timing belt replacement!) Here's to another 100,000 miles!
I'm a woman. I know very little about fixing cars but you explained this in excellent detail even down to the size of sockets to use. I think I am going to give it a go since Mechanic shops keep scamming me by telling me it's a bigger problem without first ruling out the smaller problems. They go straight for the jugular which has cost me thousands of dollars for my little 94 Corolla. The issues, my corolla has been experiencing are: 1. high rpms without acceleration. 2. Dead battery (replaced 2X in a year with brand new battery) 3. Alternator has been replaced same time as the battery 2X with brand new alternators 4. Turning on the AC seems to make the car want to stall. 5. O/D light keeps flashing. I think I may have a grounding issue which Mechanics immediately dismiss and don't even bother to check or it may be a dirty throttle body and throttle body sensor. I think maybe these two things could be the cause of the parasitic draw. I will try cleaning the throttle body and will report back in case anyone else is having these issues.
Hello Lady. And Great comments. Here are my advices: Do the following things: 1) Buy a used Throttle valve in good condition for the intake manifold. E.g. ebay.com Ask for a warranty on the part. This fixes the high idle. Check also gas pedal cable movement, could be stuck. 2) If the battery drains quickly, buy a good 12v battery charger. Maintenance charger. Keep it on weekly. That way the battery won't run out. And let me know when you've done these things. Good Luck Lady! 😃👍
@@PeterFinnTheCarDoctor Hello Man. Thank you for the tips. As far as a battery charger, I am looking for the solution not a bandaid. Thank you again Man.
Peter, You give newbies and your viewers the best, clearest and thoughtful angle shots and instructions. What video camera and gadgets are you using to help you do that? So, can the throttle body be properly cleaned with good results without disconnecting the (3?) coolant hoses? thanks.
dude your videos are very informative and helpful! I was able to change out my IAC valve on my 97 prizm (toyota 4a-fe motor) thanks to this vid. I had additional hoses on top of the throttle body that have to be takin off but other than that it was 1:1 for what i needed to do to my car. For anyone with troubles with the car not being able idle without it revving up and down, scoop yourself a new IAC Valve and that should fix it, it fixed mine!!
Agradezco infinitamente sus videos soy de Chile y tengo exactamente el mismo automóvil ya hace 23 años , y jamas le he hecho mantenciones al cuerpo de aceleración y ya tiene 350.000km. y con sus videos he limpiado la valvula IAC y reglaje a la valvula TPS. aparte de limpiar el cuerpo de aceleración . un saludo afectuoso y gracias por sus videos
the 3 tubes on the IAC... 2 are for water coolant and the CENTER one is for air out to the crankcase..... so if you squirt cleaner through the center one, the debris and cleaner goes into the crankcase.... do NOT do that. Catch it in a cup below the center tube of the IAC.oun
I wish u were chicago based. I wud hve brought my 95 corolla to you. I feel i hve throttle body issue. It has hesitation when accelerating. I dont see any engine light or anything but at times it runs smoother and doesnt get much hesitation as temperature is warm. I hve been driving this for almost 100,000 miles with this issue. it got 192,000 miles now.
Peter I haved 1996 Toyota Corolla 1.8lt engine.It have 209.340 miles,I have it with me for more than 5 years I haven't change the spark plug and it have a good power since I have it.0nly I replaced the air filter tway or 2 time,in 5 years
Hello Peter, I have some questions for you. What is the purpose of the lower (thinner one) cable at the throttle body? Also, does this deposits of black are result of infrequent air filter replacements or it is just from many years of exploitation? You, at some moment in video, mention about "air console temperature sensor". Is this same for MAF sensor or it is located at some other location? Thank you
Thank you so much for the video Peter! Shall the manifold entrance be cleaned too with the carburetor cleaner liquid since we are just there after all the part being disconnected? Is there any harm in doing it that? Would the liquid damage the attached hoses? Thank you for any response you may give!
no the manifold shouldn't be cleaned with this liquid just with dry towel and here he missed to plug off the sensor and clean it with DW40 and didn't clean all the holes of throttle
Great information as always. You are always my “Go-to” guy when it comes to maintaining my 94 Corolla 1.6 I have a question though... what is the name of the hose under that throttle body? I had a small leak at the end a year ago and I cut the bad end off and luckily was able to have enough hose remaining to stretch to the nozzle on the block. I would love to replace with good oem part. Thank you!
Peter....as always, thanks for another excellent Toyota repair video! I especially like watching your videos because you obviously like Toyotas and think they are quality cars (which I agree with). Got a quick question....95 Avalon XL...cleaned the throttle body without removing from the manifold. Is that ok? I saw a video from someone who was saying that this wasn't a good idea because the spray cleaner would travel through the idle air control valve and then down the water bypass hose on the throttle body and into the crankcase. Is this true?
thanks peter very informative, by the way is it ok to clean the throttle by not disassembling it? i mean can you just open and close the throttle by pulling the accelerator cable and spray carburetor cleaner into the throttle body? will that be ok too?
I have a 2001 toyota corolla S automatic . When i put it in drive Or reverse i get a small vibration . When im driving there is no vibration. Can this be the motor mounts and or transmission mount ? It only has 55,700 miles on it .
thank you for the video Peter it helps me a lot .. can you also post how to replace the fuel tank gas of a toyota corolla 96 because the fuel tank is broken so i have to replace it
Hello Mr finn, thanks for the vids very helpful. I have 2 questions , we have the same engine , is there a maf sensor in that engine ? And do you need to remove battery , when you clean throttle body ? Thanks in advance.
I did an obd scan on my car (1988 toyota celica 2.0L A/T) and the result was 51. 51 - Switch signal -A/C switch ON during diagnosis Wiring, A/C switch, A/C amplifier, ECM 51 - Switch signal -closed throttle position (CTP) switch OFF during diagnosis Wiring, CTP switch, ECM 51 - Switch signal -park/neutra! position (PNP) switch not in P or N during diagnosis Wiring, PNP switch, ECM My car has this acceleration issue for a month now, it cannot go uphill. I did these things trying to solve my acceleration issue, still not succeeded -changed fuel filter -cleaned maf sensor -air filter is in good condition -cleaned throttle body -clean air intake tube -cleaned throttle position sensor -changed my ATF (drain and refill method) -changed AT filter -cleaned AT oil pan and magnets -changed spark plugs -adjusted the accelerator cable according to the manual When I really push the throttle pulley to really close the valve , the obd1 reading is normal. Interpretation on the result of 51 and any suggestions?
air leak somewhere same happened to me my exhaust had a hole and it was leaking air so idle was at like 1500 and senors kept trying to bring it down to 1000
Hello Peter. I am currently restoring my 4efe 1995 corolla. I am wondering if I should do this and what would be the benefit that I would gain? Thanks for the info
Hello, I have a 91 Toyota Corolla and I just did a full tuneup on it but ( thanks to a lot of help from your videos) but when I'm driving it will start to tug but only when I am in higher RPMS. I'm not sure what is wrong any ideas?
I have a Toyota Corolla 1991. The fuse box with the 3 fuses on left side that connects to battery broke on me. The part that connects to battery broke. How can I find a place that sells it? So I could replace it. I cant seem to find the fuse box even if its the whole thing with positive cable connected?
Good friend I have a corolla 1991 carbureted and where is the intake manifold there are traces of oil and the car fails me in cold but when it is hot loses the fault, wash the carburetor and intake manifold and stay well for a day even in cold , then the flaw came back, any idea of being a friend could you help me?
I have Carina AT170 (1990) with the same 4A engine. but it only performs 6Km for 1L. any advice to make it right? I recently bought the car and have replaced the air filter and the plugs.
Hi mr peter I would like to ask you a question = you cleaned the idle parts and how do you oil the idle motor. what is the name of the oil does it need any oil ?
I just replace the IAC in my corolla because the other one has the car very accelerated, my question is this what happened is you are in idle and is you block the small hole which going to the IAC valve , should the car stop.,,,, because i think my whithout the IAC connected is more that 1000rpm so i am thinking that is taking air from some point since is i block that hole should shut down the car dont you think.?
Why is that my AE101 car with 1 liter petrol only give 7 km-At the same time during normal idle speed show 1500 rpm.When air condition is ON it drop to 1000 rpm.Whats the proper reading should be when car is at idle speed AND how to solve fuel problem?
hello my friend, i have one question i have a 1994 toyota corolla liftback and i have a problem with the throttle body make a noise like a whistle do you know why ??
hello sir, my Toyota corolla 4a-fe 96 model, has high rpm idle at 1,250. when I lower the idle, it returns up by itself, I had the engine throttle body and IAC cleaned already, but still the same.. any idea what's wrong sir? thank you
I've got 1993 geo prizm lsi 1.8 litter with 46.000 has a idle problem sometimes it won't idle down when It's in neutral or park I've cleaned throttlebody it still does it but when I let it sit a few minutes after I've been driving it ill start it up runs great would you have an idea what it can be thanks love the channel!!
hey I have a 1991 Toyota corolla my problem is. it's starts up just fine but when I put it into gear it wants to die on me I did the tune up on it new plugs wires distributer cap and rotor fuel filter any ideas what it could be it's a standard transmission
Come on man....you should have disconnected ALL sensor connections , and vacuum lines, then throttle cables BEFORE loosening throttle body...completely backwards on his approach...follow this dude at your own risk...
Hello! I have a Corolla 94 with 7afe engine but i need pass the scanner and I'm not getting. is there any software or update that i need to install on the scanner?
i have a 95 corolla. I had no issue with it till once its ignition coil went bad . I took it to mechanic shop, they fixed that but since then my car has hesitation while speeding. I have replaced so many things on it like plugs, wires, distributor cap, oxygen sensor and fuel filter but it still stalls/ hesitates while accelerating. I don't know if its a engine wiring issue or throttle body or something else. but I have been driving the car with this issue for now 11 years and frustrated as to what the actual problem is. I don't want to take it to dealership since they charge so much just for a diagnose. any body know what the issue could be.
thanks, one more thing to add. I have noticed when its cold weather it does it a lot more than normal. In summer it still does it but you can feel it running a little better. so temperature is also a factor in its performance. would that be something else that I need to look into?
@@PeterFinnTheCarDoctor Hi Peter I've been watching your video n i learn a lot from it I'm working on my wife car at the moment it's a Toyota Corolla replacing a timing belt
