Post runs rough, sound like a tractor they say?S~O~S

d
my once was turbo'd, not its not, i blew a head gasket and tore it down and to find that i also had a piece of my piston missing, so got another block, new rings and pistons, new, crank sensors, timing belt, 2 new coil packs, all new gaskets,.

since this new block i have torn motor down 3 times, everything is on time, i think where the dyminds our north on oil pump and cam gear, new plugs, maybe 2 minutes run time on them, intake side were clean and exhaust side was black with carbon?, did another compreshion test and 1,2,3 plugs were wet with raw gas, but number 4 was dry, ????? bad injector?note truck only has 90k on the head and everything but block, please help

double check and triple check your ignition firing order and that you have your plug wires plugged into the correct spot on the coil pack

I remember one member had that issue because he followed some documentation that was wrong and was told by a tech about the error in the doc. But I can't seem to find the exact post.

ya everything is hooked up right, got new injectors and ecm, didn't change anything, so far everything on this engine has been replaced, now about the timing, just to make sure im right, the diamonds our supost to be facing north on the cam gear and oil pump gear, and the crank lined up with the tc mark on the timing plastic right??

hey everyone i found out what it was, when i went to change the timing belt, i had held a crow bar to the timing gear so it wouldn't move, and had a breaker bar and a cheater pipe to break the bolt loose on the harmonic balancer , and cam to that i moved the part where the timing mark is on surpertin belt goes, about 2 inches counterclockwise from where it was suppose to be, so every time i thought it was timing marks were lined up, its was really about 30% before top dead center cause of rough or no idle, I Replaced the balancer and it runs so great~! good luck everyone, and thanks for your inputs
