well couple days ago my 3s started acting up, rough idle, hesitation and missing alot. So i checked the plugs and they looked worn so i replaced them along with then distributor cap and rotor. Now it idles fine. But, whenever the car is warmed up and out of the "safe mode" it kinda looses power. For example, when im driving 1st and 2nd are good, not affected, but my 3rd 4th and 5th the car sounds like its farting, like a prrrt prrrt prrt sound, lol best i could do. if i accelerate slowly and build boost slowy it doesnt do it at all. but say i wanna merge into traffic or take off and go wot it does the prrt thing. So i thought boost leak cuz its doing it under boost so it seems load based. checked out my piping, everything solid, not hissing from pipes or intercooler, havent done an actual boost leak test but i will soon. i did notice on my dp i had two hairline cracks. both right after the 1st o2 sensor, and im wondering if the 2nd sensor isnt seeing all the exhaust and maybe trying to compensate but i dunno. any feedback would be great guys, thanks

your bov might need adjusting.

do the boost leak test too.

Change your spark plug wires!!!

"So i checked the plugs and they looked worn so i replaced them along with then distributor cap and rotor"

i didnt change the wires when i posted cuz i was waiting on them from the dealership, i was posting to see if anyone could shed some light if it were something not with the ignition

most of these issues are cause by one of the following...

1. boost leak (check intake from afm to turbo too)
2. ignition
3. afm
4. TPS
5. coolant temp sensor
6. knock response (easy to monitor with the tvsv mod)

go down the list and check them all one by one in this order.

came home and my new wires were here, put em on and problem solved.
