It's an 03, just incase it makes a difference.


Anyway, it was the second time I actually 'got on it' and two things, it feels like it has no power around 5k rpms, and around those rpms, it was definetly breaking up ... sounded like extreme detonation, but the car is 100% stock



any ideas what it could be?

 

Intercooler hose popped off?

 

that could explain the no power, but not the detonation sound

 

Bad gas?

 

its running on a full tank of 93 octane gas :/

 

could be bad plugs.if the hose is popped off the evo would be really running like crap and barely go 5mph.

 

i got some NGK 7s and asked like 5x in my other thread if they would be fine and no 1 ever answered me .... it also does seem to haev a little 'mis-fire' my friend said at idle

 

ngk bpr7es would work fine and gapped about .24-.26,thats what i use on my evo and changed every other time i oil change.

 

i beleive they are pregapped at like .33 or .30 would those be fine? if they are i can go change them right now then go out and get on it and tell you if its the same or different.

 

thats kinda big still.if youre planning on going with higher boost you would want to have a closer gap for a more solid spark.but since youre stock it might be fine for now.

 

how many miles ? a tune up may needed

 

Gap the plugs at .28 or just get some NGK iridiums at the 7 heat range and stick them in.

 

Yep, I had the intake hose pop off my throttle body and the car just flat-out died. I imagine any hose would act the same.

 

well i dropped it off at the dealer today with a list of crap for them to do ... im sure there will be 'no problem found' on half the stuff

 

Read your owners manual...... You need to gap the plugs closer than what you have them at... No matter if your running NGK 7's or 8's..... If not you will blow the spark out and it will run like crap.
