This started happening in the winter, when ever the stock turbo starts spoiling up the car starts stuttering at wot it, and at higher gears it will start doing it at 6k rpm and won't accelerate anymore the stuttering sounds like it's back firing but but very rapidly I changed the fuel filter and it seem to stop buy starting doing it again. The stuttering onlyhapprns at night or cooler weather. What do you guys think it could be?

 

Anyone?

 

fuel cut? do you have a boost controller or anything on your car?

 

Yes I do I have a ebc greddy pfec II

 

spark plugs possibly

 

That's what I was thinking how long are the plugs good for on stock turbo?

 

Mine likes to do that from time to time. Put in new plugs and use a smaller gap. My gap was too big and it was blowing the spark out.

 

I am almost positive it's your plugs!!! Check those mugs mang!! ALotttt of people don't change those on the right mileage and just let it keeeeeeeep going like it's nothing.....running 40k+ on the SAME Spark Plugs you drove off the dealer with! :X Ahhh....gawd.

 

i use copper plugs and do mine every oil change. why not? its only $5-6 and another 10 minutes with the hood open.

 

Alright thanks and I will

 

well right now my car is immobile, sent the stock turbo to get upgraded to the red, should I run the same ngk irradiums or some different ones?

 

I would run the irridiums. I tried a set of platinums once and one trip around the block and I was putting the old ones back in. Car ran like crap, put the old ones in and good as new.

 

Not the SAME irridiums. Depending on mods your going to want to use a colder plug...maybe 2 steps colder (like i said depending on mods).

 

Well I'm also gonna get some inj 1000cc some cams and tune on e85
