OK heres the situation. The car about 2 weeks ago just driving calmly started to sputter on me and lost almost all power. All of a sudden the check engine light starts flashing and throwing misfire codes. I take it home and tear out the plugs. the # 1 plug gap had no gap and the rest of them were fine. Took it and get a compression test done and I have compression of like 175 across all cylinders so i dont think its internal. The only thing i have done lately is put a new 02 sensor in it (Bosche) So i drove it home after the guy said it stopped sputtering and it started up again but no misfire codes. All of a sudden like 30 seconds later it does it again on and off everyonce and a while. The fuel pressure stays the same when it starts sputtering and im running the accell injectors from hahn and the cartech fmu. not sure if its a fuel problem or what. ANyone ever have this happen? I checked all the valves and they are all there also w/ no cracks or anything.
you may have cracked a piston and sent it in the CC, likely went out the exhaust and hit the turbo.... I have had that happen. maybe take a look into that cylinder again, check that piston, if something smashed that plug shut, it wasn't air or gas, so something got in there....
compression @175 is low over all 4 and having a broken piston suprisingly didn't lower my compression...
if pistons are fine, then something up line may have broken off, or simply the electrode ceramic broke

Yea but would it cause the car to do that on and off like that instead of constantly because i know if it was a major problem like a piston then it would do it all the time and not occasionally.
