03 , 2.0, Stage 1 , Cobb SF / Accessport / I finally got around to pulling my first data log. I was hoping someone could help me out.
About 2 months ago, my suby started acting really strange in cooler conditions, with throttle wide open, in either 4th or 5th gear, about 70+ MPH. I can seem my power band pulses up and down, RPM's jump about 10K or so then back down. All while accelerating. I am not sure if it's a boost or fuel issue. I have noticed it at two different ranges within around 3-4K with throttle about 1/8 open, then again at full throttle higher RPM range....Any thoughts? Dirty injectors, air leak?
This wknd, I installed brand new Coils. still same issue..
