hello all
This is the first time I have post so bear with me please.
I have a 1988 cherokee Pioneer, auto,4.0
It seems to missfire badly When I get to cruising speed.If I give it the gas it clears up. As soon as I resume cruise speed it starts missfiring again. I may be wrong but I think its when the trans shifts into drive. If I drop into 3rd it straghtens up. the Engine is freshly rebuilt.I have replaced the tps,o2 sensor,coil,ICM,cps.
This is getting exspensive. I sure could use some input.
