check compression imo.
i kept getting 302, and swapped ignition setup to cyl 4, which made cyl2 worse, then ignition back to cyl 2, and still idle miss, and then swapped 2 and 4 injectors, still missed at idle. gets better at load or part throttle (1000+ rpm or better, and mis seems to disappear, as not as bad and not showing up on cobb roughness read, but still a dead cylinder basically), but unplug and plug in coil while running, same with injector and no change to idle. ended up checking compression and found cyl 2 at 50 psi at b
est. cyl 4 gave me 125 psi.
vac leak checked and none found. no leaks found during spraying it all and watching a/f data and rpm, etc. yet didnt have ability to grab a better scan tool to watch fuel trims.
avcs and oil control valves etc would all cause both cylinders on that bank to act poorly right?
very informative thread. just read all 35 pages this am. theres a few ppl i wanna ask on a more personal level what they spent on repairs, and if thats cool can we do it via pm if you dont want it publicly?
financially unsure if i can swing the deal to keep and repair the car. but i wont knock the car. i love my lgt. bought it in dec 09 with 40k or less on it. now in september 14, it has 145k and has been great to me. no issues until recently. car is just now starting to need repairs in various spots. hell my roll center kit endured 90k plus miles and 4 yrs of dc commuting. oem turbo and engine. catless exhaust pipes, turbo inlet and spt intake and stg2 ots cobb tune. been good to me. yea it has blowby or excessive crankcase oil coming into pcv etc. now im looking at engine related repair or replacement etc with further diag yet still lein on her. (got a job further away than when i bought the car. never figured shed see so many miles so fast)
