Not sure if it's a misfire or turbo related. When I roll on the throttle car runs fine and at cruising it's fine. If i mash throttle in any gear, higher the gears are worse car misses and jerks and seems to flatten out like it's pulling timing. Could this be a turbo hose collapsing? Anybody have a similar issue? Would I be able to pull a code with an OBD11 code reader? car is not showing any lights on dash. It's an 2001 tt 225hp with revo stage 2 chip.

PS Just cleaned MAF, New air filter no change still stuttering under load, Although I did get a check engine light. Is there any way to bring the code up on the dash without a reader?

 

Change your sparks and gap accordingly for chipped a car. $30.....priceless. I'm suprised you did all you did and never changed the spark plugs.The symptons you have described are classic and a must.

 

X2........

 

I changed plugs about 20,000 miles ago, But I'll go pull them and se what they look like. Would you get a Check Engine light for a bad plug? I Got a light yesterday but only for a few minutes, I need to see what code is stored also.

 

Also CLean and many change your MAF my car used to do it no matter how i hit the gas I changed my coils, and plugs and no diff. Also check the Vac and boost lines.. But its prob your MAF.

 

Changed plugs, made no difference still have miss under load, I need to get this code read

 

Update: fixed miss , it was #2 coil, Runs like a rocket now

 

how do u tell if a coil is bad? Im having the same problems
