I read similar posts, and almost all of them fixed their problem. I tried those parts they fixed and none of mine work.

After it starts, it will idle high (1500-1700rpm) then die 3-5 seconds later. I've replaced the ICM, dizzy cap/rotor, tested pick up coil, tested ignition coil. EGR works, TPS works, MAP works, IAC works (might buy a new one to double check), no vacuum leaks. Fuel pump works, injectors work, FPR works.

I can't for the life of me figure this out. My dad, even with his experience, can't get it. I know the oil pressure switch/sending unit wasn't working before, I replaced it and still doesn't work (wire looks exposed).

If I throttle the gas, has to be worked, it will run for 20 seconds then loses power and no amount of working the gas will keep it running.

I did find a disconnected connector near the knock sensor (isn't that), and couldn't find where it belonged.

I couldn't find any vacuum leaks, but I'm thinking there could be at the TB (the TB doesn't look like the right one, either) but no codes come up with the MAP.

The motor was possibly swapped to a 350.

I'm thinking of replacing the TB. Or just going carb. But to save me the time and money, anyone have any ideas?
