Tell me about it. My car only has 15k miles on it and already this crap? Can't wait to see how it runs 5 years from now. It's under warranty so I am going through the dealer before I spend a penny on this issue. What a pain....

 

i had same promblem and i took it to the dealer and they said it was the trans
they said that the trans wasnt shimed right from the factory and causing alot of movement in the trans, knock sensor was picked up as a engine knock thats why you got a misfire code .
Its all under warranty and they will rebuilt your trans

 

Stuff like this gives me hope. Did they fix your tranny????

 

I still believe that making the crank angle sensor on the tranny less sensitive will work. Just locate the tranny crank angle sensor, remove it and install a piece of rubber tubing between the sensor and the tranny. The more you isolate it from tranny vibrations the less noise it will pick. That means that the ECU will not hear the noise from the tranny as knock and will not trigger limp mode.

Please try this. It might work and you will solve a problem that a lot of 03-04 EVO owners have.

Edited: Correct my mistake. I used knock sensor when I should have used crank angle sensor

 

Please try this: Pick up the manual and find me where there is a tranny knock sensor. Gotta love the wealth of information here.

 

OK. I'll look into that. Just curious if anybody out there did have to get a new tranny or a rebuild and if it was covered 100% by warranty. I'm just curious how many have solved the problem for good through dealer/warranty work and not after market tranny rebuilds from race shops and stuff. I want to be confident the dealer can fix this for free no matter what they have to do. So give me hope guys! Please.

 

You are still sore from our last argument, aren't you At least I am not hyping a product I have to sell so I can make a buck

I really hope that this works for him. We had a similar problem on an 02 Sentra Spec V. The knock sensor was just too damned sensitive and it was picking up engine noise as knock and pulling timing and causing a loss of hp. People were either using a dummy sensor or isolating the sensor with tubber tubing or moving it to the fire wall. That helped them gain hp.

I believe somethng similar might be happening here. I hope he tries it. what is there to lose? He has tried everything else and it did not work.

 

If you want to make sure that the dealer will fix the car under warranty, then return your car to stock with ZERO aftermarket products and take it in. They will have to diagnose it and determine to their own satisfaction that it is the tranny. They more than likely are not going to do a tranny rebuild until they have tried everything else including a flash. You might have to go to the dealership multiple times before they give in and order a tranny rebuild.

 

I appreciate your 25 posts, we have sold 17 zeitrionix units as a results of your thread bumping.

But that has nothing to do with this subject or thread.

Your advice is ridiculous. You have no idea what you are talking about. You are advising people to search for a "tranny knock sensor".

There is only one knock sensor and it is in the back of the block.

Tries what? Looking for a tranny knock sensor that does not exist. How bout this. You go buy a shop manual for the Evo, and when you figure out what the hell you are talking about, you come on back and post your expert opinion.

Better than that, go back to working on your Nissan Sentras.

 

+1 I agree, this nj1266 guy has no clue what he is talking about.

 

You are sore and it is clear by the fact that you post whereever I post This is the second time you posted in a thread right after I did. You accused me of attacking Dynoflash in another thread when I told a member not to flash their car until they solved their p0300 problem and I showed you the evidence that you are worng and that it could happen.

Now, I was commenting based on what another member said:

I used knock sensor instead of crank angle sensor and I admit that I made a mistake. But the THEORY still applies. If the crank anlge sensor pick up point on the tranny is triggering this, then isolating the vibration from the tranny should help.

note that I used the correct terminology before.

So it was an honest mistake on my part. And the nice thing is that I admit my mistake unlike you. Remember that comma

The guy has tried everything else short of a tranny rebuild. What harm could trying this do?

 

I think you also need to buy a Zeitronix from TTP

 

Yeah I knew what you meant

 

You have absolutely no respect for evom and should be banned.

 

Also, the car is basically stock. Just a TBE which my dealer could care less about as they said it would have nothing to do with this problem. Unlike the ball-busting Mitsu dealer in Hagerstown that was giving me a hard time about my test pipe. Good thing I never took it in there and never gave them my VIN just incase. I agree that I will have to take the car into where I bought it a few times and keep trying the easiest and cheapest solution until it is resolved. A pain, but at least it is free. I just want to know how many people have actually solved the problem by going through a dealer and having warranty work done. I know a lot of people will say "buy a creader" and thatll fix it. That wont fix it, itll just hide it. Or "buy an ems" thatll fix it. Uhh....I'm not dropping almost 1500 bucks on a car with 15k miles that has over 3 years left on the bumper to bumper.

So has anyone actually gotten the misfire problem completely fixed through their dealer/warranty???

Thanks!
