misfire issues

[briscojl]

First of all let me say happy thanksgiving. i am still full from turkey day that i cant even see straight. second i had a Cel come on about a week ago and it was a misfire on cylinder 4. The shop where i took it says that it happens to turbo cars all the time. so two weeks go by now the same problem. now what do i need to fix it because i just dont want to have to keep clearing it and clearing it. my car is still under warranty so should i return it back to stock or it is just a quick change of plugs that i need? Also if thats the case what plugs should i use.

make it as stock as you can and take it to the dealer. i dont have a turbo car and i had a check engine light that came on and it went back off so i didnt worry about it. Then when i took my car in later for just its regular check up they asked me why i didnt bring the car immediately to them for them to fix the CEL(I was running lean do to a hose being loose). Even though my car isnt turbod i do have mods that will void my warranty if they are seen such as motor mount short shifter and pulley kit. I just take whats visible off before goin. they should fix it right away as long as you have it back to stock

all i have on the car right now is the CPE intake and HKS BOV. would any of that cause me to run lean?

bump....any advice woulde be greatly appreciated because i only have 28,000 mi on it and im thworing CEL's already.

Intake and BOV won't cause you to run lean. To be honest I think there is a guy having a similar problem in another thread. I can't find the thread so maybe not........

what could i do for now to try to get this CEL off. people have recommended a fresh change of plugs and wires,but i dont know what are the best kind to get for this car and where.

Shoot a pm to streetunitmark/chris, or to Rhoadblock. A lot of ppl have gone to 1 step colder plugs.

they only have aftermarket plugs for our cars and not coils? why is that?
