Hello, I'm new to this forum and could really use some help. I'll tell u the whole story so I don't leave anything out. It's a 1989 camaro rs with a 350 tbi 4 bolt bolt main out of a truck. It's bored .040 has a few upgrades. The throttle body is a holly 670 cfm. The engine has about 30k miles on it. When I bought it had 20k on it. It always ran a little rich but it was fast as hell so I didn't bother with it. Suddenly one day it ran perfect and the next it wouldn't even start. B4 I forget, every part on this build was brand new. No reused parts even the wiring if that matters. I put new plugs in it and fired it up. It ran very bad. I notice it was just dumping in the fuel. I changed the temp sensor and it helped a BUNCH. But it's still way to rich. It runs like hell till it's warm but almost smooths out but u can just tell it's to much. I've tryed every trick I know and the car is only about 80%. The problem I'm having is the electronics. I didn't build the car and I'm new to all the electronics. Idk how to test them or what might be causing this. PLEASE HELP!!
