Need your brains! 3.8 SC
I need your brains on this one. A 93 SC with a brand new engine. After assembly and installation the car has had 1 probelm. Fires up when cold great. After roughly 20 seconds it starts to miss mildly with a rough idle. Moments later you gotta keep it running by light reving, its get so bad with some popping, you gotta shut her off. Now, you turn the key it will fire back up running rough. I noticed that once it has any heat in it at all it runs terrible, cold its ok.
I have pulled the timing cover and checked the crank/cam timing. I have pulled the cam sensor and used the cam sensor tool to insure that all is aligned. THe cam sensor originally wasn't causing it to run with a different firing order. All that has been fixed and its how it should be. I replaced the Ignition control module as the last one tested bad.
If the crank sensor was bad the tach wouldn't work, it does work. Im about ready to burn it down! A real money pit!
Any help is appriciated!
