IM still running into issues. Same Idle misfires and the occasional stutter when i gas from a dead stop. absolutely no misfires under boost or heavier throttle. Misfire travels throughout cylinders. Some days its 1 or 2 or 3 or 4. I've cleaned injectors (both), done compression test, plugs coils everything.

Please take a look at my datazap. Car still runs fine except the misfires. ITs crazy that this has been a years worth of misfires and the car still runs but im hitting a wall om rectifying this issue. Its getting more and more complicated for me to pass inspection as well here in NY. ANY help would be greatly appreciated

p1170 <<----NEW CODE. NEVER SEEN THIS IN MY LIFE LOL

I forgot this is a IAG 800 w/ built heads and stock Cams.

Have you tried a new battery?

How much Googling have you done? This pops up pretty quick:

Too much tbh. So far ive done Vacuum leak check, compression test, changed all the gaskets, cleaned the the direct injectors, cleaned the port injectors, changed spark plugs, got new coil packs, changed cam sensors. im stuck

I had p219 and p119s on a built na engine but could never find the source. My tuner finally just deleted the codes. I've had the misfire and other codes with a vacuum leak.

Did you new gaskets include exhaust? Was you vacuum leak test with smoke?

Yes with smoke. and new exhaust gaskets. i know some people see the misfires but dont feel/hear them but i do with mine on occasion.

This guy's problem seemed to be partially solved by putting stock flywheel back in.
