GREETINGS, I Just got installed my reman engine and it starts beautifully and hums like a sewing machine. I've replaced all the plugs, wires, and a fuel filter. The problem is it misses while driving...all through the rpm. It will miss a little and then it will smooth out and run awesome...but then it will start to miss again. At an idle it ticks along smooth as can be then in about 3-4 minutes the idle drops 500 down to 500rpm and just about dies....then it kicks back up to normal. I've read on here about the TPS, (also I have no CEL on the dash) and also about a coil pack. I have not changed either since the new motor. Any ideas? Thanks
Also, noticed that when it is missing....it doesn't respond to hardly any throttle input..except full throttle. It will maintain what it has, but won't accelerate unless almost full throttle.
