Ok this has happened a few times and it always happens 2-3 times in a row. I will be driving in 5th gear around 60-70mph and when I push the gas the car acts like it is missing. It has no power and it shakes like crazy. Then it acts fine then repeats itself maybe a few min later, then all is well for say a week or 2. It does not happen everytime I drive. As a matter of fact it started about 3 weeks ago then it did it again yesterday. It did it 3 times with in say 45 min then not once again. Both times were on long drives.

 

it looks like you got the infamous tranny harmonics P0300 issue. do a search on it. there are a lot of people (myself included) that have this problem. i'm guessing you have a higher mileage evo?

 

Could be one of 50 things depending on the mods and the most recent one prior to this happening

 

+1, i used to have the same problem good luck with that if u don't have a warranty

 

For some reason my car doesn't have the po300. It has 60,000 miles and is an 04


It would be more beneficial to datalog the problem and show a list of modifications

 

p0300

5th gear is loose, causing a rattle.

 

Well I know I have that damn P0300 code, buschur said it would be from my twin disk clutch. I have hard intercooler pipes,exhaust,cams,fuel pump and a reflash. The Reflash has been done for months and it never happened till a few weeks ago. My car has a warranty on it although it does have 71,000 miles on it.

 

Yeah mine progressively worse after my ACT clutch install at est?56k clutch install. now my 5th gear has a rhythmic sound most audible between 55-69 mph. at the early stages it wasn't noticeable, but after 20k miles later, now is very audible. It's to the point that once I reach 70 in 5th i misfire everytime I press the gas. 5th gear just wears due to the gearing (sort of like a bicycle: pedal gear <the biggest >rotating the smallest 5th gr <rear wheel> at least that's how i made sense of it) Every one revolution by pedaling, equals 3 rotations on the rear wheel (5th gr) . I've also read that the input shaft develops play after high mileage which seems helps to trigger the p0300.

 

So what you are sayingn is I should have the warranty company pay dan buschur to rebuild it

 

+1 Definately it happened to one of my friends evos not too long ago

what warranty do you have that covers the tranny after your IC pipes, exhaust, cams, fuel pump, and reflash mods in addition to 71k??

I think we all need to pick up this warranty

 

All that has to happen is for a repair faclity to say the part(s) need replaced. I just has a new control arm and a rear axle replaced.

 

Clutch and Trannys are not going to be replaced under warranty

 

why is that? It said bumper to bumper. I was told that they would replace the motor if it blew

 

Does this p0300 happen at anytime or when the mileage gets higher?
