Hi i need some help were stuck.
Replaced: Distributor cap
TFI
Spark plugs & wires
TPS sensor & connector
Fuel Injectors
Fuel pump
Fuel filter
Crankshaft hose and thing that goes in as well as breather
Battery
ICM
Map sensor and connector
FPR

We have also changed oil done seafoam treatment in gas and oil as well as Lucas oil after the oil change, we've checked fuses wires etc and it still is hard idling, now under load, rpms fluctuate and there is a misfire. We checked the spark plugs again and the 6th had black ash so we got a new one and put a no foul stopper all the others are fine. PLEASE HELP!

When,you timed it did you unplug the battery, unplug the PIP SPOUT wait about a minute or two hook battery back up,start it adjust timing to about 12 degrees set the screw plug PIP SPOUT back in if that doesn't fix it I suggest goinf,back over double,check all grounds and make sure all spark plugs are correct. I did all that stuff plus some,more and,it turned out I had 2 wires backwards flipped them worked perfect now also put petroleum jelly unscented on,your connections,to,make,sure its all contacted
