I have been slowly putting this car together. It is a rebuilt motor with a Comp Cams stage 1 cam, 1.7 roller rockers, and the full blown MP performance package. All the sensors on the motor are new. My original problem of poor timing and backfiring have been solved by getting 5 & 6 plug wires in correct position.
Now the new problem. It will start easily, runs kind of smooth at first then gets rough as idle slows down. If I try to give it gas to keep running, it's real rough and I have to keep going up and down with throttle. Too much pukes it out. After a couple minutes of that I can't keep running. I can start right back up and go through the same again. Yesterday I kept doing it until it warmed up. Once it did, it stayed running on its own. I adjusted 2 screws on TB and have the idle around 800 rpm. If I give it gas, it still doesn't like it. While idling, I sprayed ether around lines and couplings to check for leaks. No change in motor so I'm guessing no leaks.
Any ideas would be appreciated.
