Code P0300 Diagnosis And Repair 

Thanks, he seems super happy. He was hoping to come here in the first place since they just moved up and several people told him about us. But when he first called we were about a week out with appointments.

Plus you get the satisfaction of doing it yourself! Blessings.

So smart I do the same

Hay tim. You have the best review for this tool and awesome instructions on repair. I bought this tool based on your review, but the topdon plus I have doesn't have a misfire monitor like yours. Any ideas

You mean stealership!

Also helps you diagnose things faster in the future the more familiar you get with your particular vehicle.

Ever get it fixed ?

Thank you! I got lucky again. It obviously has engine wear, loose valve guides and looks like probably an injector issue on bank 2 from the fuel trims but the customer is super happy to have it running smooth for now so they can get through this year hopefully and budget for a long block or replacement vehicle in the future.

You mean the Stealership!

Dealerships see it as a license to steal, the one up side is that a honest guy with a solid knowledge base and a good selection of tools, a place to work and a good scanner will never be out of work !

Thank you. I appreciate the kind words. Take care.

Very nice. Yes we see intakes leaking and knock sensors and harness issues quite often around here as well. Glad you got yours running like a top. You take care!

Ed Spencer so it was an intake gasket?

Did you get any knock sensor codes?

Change spark plugs and oil change end result car started losing power and was told that I need to replace the transmission

Brian, I’m so glad you stopped in. I’m sorry I was short handed and busy. So glad to meet you. I hope your time up here is a blast.

@@ThecardoctorTV I understand that you are a busy man which says alot that you took the time to visit. You're a good man and I'll continue to be a strong supporter!

Thank you. So this has been about a year now and the truck is running strong. Still using oil and he needs to put a motor in it but 10K miles and 12 months of driving for a set of plugs and a little labor has been worth it for him. Take care and thanks for the sub!

Did you do a review on one of these too? haha, ill have to go check that out. Seems like a very affordable scanner for its capabilities. Good of you to drop by my shop!

+The Car Doctor I agree seems to have many functions

I would buy one of those for sure since im all about saving time! Must be one of those really expensive tools that only the dealer has access to. darn

Thanks, I think a tool like this would be a great help even for folks who aren't seasoned mechanics. I see it has tips on specific codes so ill look more into that feature to see if it gives good information on where to look for problems with specific codes. If that isn't enough there is always RU-vid and I tell you what, I have learned a lot here!

The Car Doctor Hi Tim, Thanks I appreciate your help. I very grateful that I found your channel. Your videos are always educational. I forwarded your videos on to several friends and relatives over the past few months. I hope you don't mind. Thank you for your help. I will appreciate it very much. Stay warm my friend.

Thank you. I look forward to using it for more diagnosis in the future.

Thank you.

People just take advantage of good honest mechanics.

There are a lot fo really great techs at the dealerships. Also a few that probably should take up another career. Not a problem just for dealerships but for any shop. Bigger the shop the easier for things like this to happen I suppose. Thanks for dropping by!

Good plan to start with Plugs, wires cap and rotor with AC Delco parts.

Texted this customer yesterday for an update. Says he has put a ton of miles on it and running great. Its very rewarding saving them money and getting to be the hero! Take care sir!

Right on. I hope it works as well for you as it has for me. IM going to use it more to try and get an idea for what coverage and data PIDs it has for other makes.

Not sure if they faked it or just guessed. Anyway the customer is super happy we were able to save them a few bucks...Like $4500 (dealer estimate)

Stealership. White collar theft.

Thank you! You take care

That's possible or just shooting big fat estimates trying to make some money or a little of both. This didn't look like a candidate for head work anyway. I would just throw a long block in it over doing the top end and ending up having to do rings and lower end six months later. I don't get it.

Totally agree Tim, tightening up the lower end at the same time is the way to go. Anything less is a complete waste of time. That way you have a solid engine and anything you add after that is just maintenance, water pumps, poweer steering pumps or belts and hoses is just maintenance when you think about total cost, just saying.

more like scam asses

Ya I'm trying to find the link or even model of that scanner. Couldnt find anything exactly like it on amazon or Ebay especially for $60. , but I imagine it's been modified and cost more now being this videos 6yrs old now. Be nice to have the live data for inexpensive,

Thank you for the encouragement. I agree with the honest part but the hard working and knowledgeable part might be a stretch. hehe

wow, im flattered just to be mentioned along with Brian. Hes a top notch guy. Thanks for dropping in!

Ron Austin I went 170,000 on the original plugs on my 2007 Nissan Murano

I'm experiencing the same issue. Changed plugs, wires, coils are fine, mass air flow. unbolting cats tomorrow to see if that makes a difference.

of course you need to clear the code jackass

You wasted money on a new cat if that was an issue your car would have thrown a p0400 code for my car when my cat went bad my code for it in my dodge was a p0420 and 9 times outta ten if it's emission related the code it is in the 400 range and very rarely will it be that unless it throws that code along with a p0300 you should do a compression test if it has low compression then it's due to a valve and if it's a major difference in reading from other cylinders you know which one it is and to go after but if it's across most or all cylinders then your engine is wearing out and unless you want to pay to have your engine rebuilt you might as well but a new car especially if the rebuilt is gonna cost you more then what you paid for for the car to begin with also trying looking at your crankshaft sensor or cam sensor if those are bad or dirty it can cause a p0300 code if not sometimes not always low fuel pressure can do the same and also check your coil packs they could be bad too I suggest coil packs next then look at your crankshaft sensor and or cam shaft position sensor if you have both then move to a compression test afterwards and go from there if none of the previous helps or fixes the issue and you have low compression across the bored then your engine is wearing out and like I said it'll have to be rebuilt or buy a new car if the rebuilt is gonna cost more then the cars worth my opinion from what I have learned

I would add one more thing. Hope you don't need a lot of warranty repairs because those don't pay well and likely go to the newbie techs. Then you might get free repairs but they sometimes damage your vehicle doing them Sad

this is sad and ugly part of the service industry. As a service technician, I was told to make a maximum bill when problems are confusing and gray to the customers.

I like it. Ill be keeping this one in the glove box just in case.

Thank you! Glad you liked it. Blessings

@@ThecardoctorTV I knew you were a Christian! I could just tell!!!

Thank you and I appreciate you dropping by the shop.

The Car Doctor have you run into many problems with the S10 trucks with the 2.2?

Greetings Nikiski! Thanks for the love.

hehehe. Can you look at misfire monitors to pinpoint which cylinder is missing? That would help save some time. Good luck

Ever fix the problem ?

@@jesse75 I did!! Well kinda, the motor was trashed. I sold the car and have not had a problem ever since. Oh, and from my caddi experiences, I'll never own another one.

Braves Fan92 did you ever find out the problem I’m having the same problems

South Texas Bass attack remove one of the o2 sensors if the vehicle runs great but sounds funny from removing it it’s gonna be your Catalyst converter

Thanks. This little unit seems like a decent tool. It would be easy for me to take on the road when im out of town just in case.

Your attitude is great, always cool, calm and collected!

Thanks, although I edit out my bad moments. That's why I don't have a live web cam mounted in the shop. hehehe

It's just guess work.
