so here heres what i have done, i did the headgasket on my car and have it started again. it was running ok after starting it up again after hg then it started misfiring bad, and running really really rich. black smoke out the tailpipe rich. i have stock inj in at the moment with a new gt2871r. so if anything i thoiught it would run lean.... could air pockets in the cooling system cause this? my spark pluugs are black and are dry though when i take them out. i checked the gaping. compression shows 140 - 145 on all 4 cyl.

and also the car wouldnt start with my new power fc, it would start when i had the map sensor pluged in but still misfire..4

any ideas would help out alot.....

thanks for your time.
