My car is royally pissing me of. Today coming home from the gym I go wot, car hits 13-14 psi but has a weird feeling and somewhat jerks, and makes a weird noise. What could this b, any input.

 

what are your mods? be more descriptive in how the car is acting

 

Need moar info.

 

Might be because you just worked out bahaha

I kid...

 

K&n intake, megan downpipe. Car runs fine when driving normal, dont know how to really explain it, only that I hit wot get sone boost and it feels like the car is trying very hard, and sounds like a sputter almost. Damn I sux at this lol.

 

throwing any codes?

 

Does it feel like it hits a rev limiter (but you haven't and it still slowly climes rpms)? Is that your normal boost?

 

^^ that was my next question. My car has been doing what you just described. Im thinkin i have a bad coil or plugs or something. and when it gets to a certain RPM it misfires and knocks everywhere.

 

Mine did what I described a couple times. Took it to the dealer, no codes and nothing wrong. They suggested changing gas stations or it could be because of high humidity.

 

did changing gas stations help?

 

U sir are correct.

 

Water in the intake?

 

i disconnected the battery last night and today it is running fine, dont know if that was the right thing to do but i sure feel a lil better. LOL

 

way to add more info lol

 

Right now it did. But when my car did that is was basically in the spring and next time in late summer. Both times was from the same station. Changed and haven't had the issue (might though never know).

 

My car used to have very loud knocking at times under boost, or what sounds like a loud knocking anyway. Hasn't happened since I went catless. I suspect possible cat issues and / or loose turbo --> DP bolts. Happened more often in the cold, which makes me lean more toward the latter.

 

If you're running mods and are untuned your car will hate you. These Bosch pcms are really finicky about fuel trims.

 

Could also be having fuel pump issues. One of the local guys I tuned had An issue similar to that. Upon logging, we found out his fuel pressure was dropping substantially right in this powerband. What kind of plugs do you run?
