i just got done dropping the motor i built into the car today, got it all buttoned up and running, runs good, but it has a weird idle either fine or surging bad..

also at part throttle it has a bad miss, but if you go WOT, it will clear up for a second, under wot its fine and hauls ass.. if you turn the car off while its doin it, and restart it will go away for a minute and come back.. I think its because i used some old plugs i had, but dosent really make since?

not gettin a CEL either..

ahh, I was hoping for more.

Good luck with the miss. I'm sure you will get this response, but is everyting tightened up? Not leaks anywhere. Have you sprayed a little carb cleaner to see if you get a surge anywhere(make sure you are very cautious)

yes to all above, nothing no leaks

good compression, going to check plugs tomorrow, all plug wires look good, just weird that its like a switch at WOT and it gets 200% better?

i've seen 2 coil packs just up and die.. and both times were after washing the engine bay. Happened to my friends stang and mine.. runs find before you wash the engine bay and after you wash it there's a miss. both turned out to be coil packs. also make sure to check the gap's on your plugs
