i still have the same problem.....fifth gear...but mine is at cruising speed usually about 80 or so...the car looses power, and you have to let up off the gas and then floor it again.......is yours doing the same???

 

yeah pretty much, and i just got back from my guys shop, yeah its p0300 code... so and i really dont notice a misfire while i drive so i dont know i guess ill just live with it like you guys say hahaha... that damn curse i mean code!@!#!#

 

26mm is quite a large gap, even if you divid by 100, still alot

 

i mean the stock gapping i think is 25? im boosting a little over the stock boost, so i mean we've gapped it averaging on how my car is tuned and other things... but i mean what did you gap yours too

 

you torque the spark plugs to 25lbs.

you want to gap them around .026

 

thats how much i gapped them

 

Why does everyone get misfire codes?

 

Isn't a p0300 "misfire on multiple cylinders"

 

I just put a mutli disk clutch in and my problem got worst 70+ mph and 3200 rpm + and I would get the p0300 code and misfire just about ever mile. I just got my creader by launch and for the first time in 2 years I have no ses. it does come on but it will get wipe put in a couple mins. I could actually drive the speed limit on the turnpike. Of course this is the first day to have it but so far I am really excited about. it cost about 32 and some change. I have a feeling this is about the best thing until you need to get tranny work. and also the creader gave me a code I have not been told about.

 

I'm having the same mis-fire issue. It was strange because it just all of a sudden happened and now keeps happening.

I feel the mis-fire, light comes on, and I clear the code. Couple weeks later same thing happens. It is strange....

 

hey silentevo 8....how far is claremore from tulsa.... I have a silver 03 w/ br stage4 mods....pm me and let me know...

 

if all of yours are doing the same thing mine was, its not a misfire. its the input shaft bearing and 5th gear synchronizer. at least im pretty sure thats what it was that they replaced. bone stock at 59k mine was doing the same thing. would start to "miss" while cruising in 5th gear. tried plugs, dealer flash and nothing seemed to help. its actually the transmission bearings making so much harmonic vibrations that the knock sensor it interpreting it as a knock, retarding the timing, and causing the "miss" vibration. tried another mitsu dealer, explained my problem and they said they would take care of it. because its obviously a common problem they didnt cause a fuss about covering it under the powertrain warranty since i was stock. :-) had em throw in the Act and 10.5 flywheel while they were in the process for a small price of an hour labor. haha. but have not seen the cel in 3k after the tranny rebuild. hope this helps.

 

Damn this sux for me

 

maybe it is the tranny b/c I have never gotten a misfire code in two years.
