Ive been working on this project for a while and now its down to the final fight. It will start, when it tries to idle down after it starts, it quits. If i feather it, it misses terrible then when i per off the gas it will die. If i floor it it will die. I put new injectors and idle control valve on but no change. Please help.

 

So what did you swap over to? Tpi or tbi? Did you use a matching harness & ecm?
Check fuel pressure. Did you set the throttle postion sensor?

 

I swapped to the the throttle body, two injectors, how do you adjust the throttle position sensor? I think it might be the fuel pump. The last motor was tune port and this one is throttle body so i think the tune port had a lot more pressure. Any ideas on that?

 

Alright. I put new sebding unit and correct fuel pump in. Its still doing the same thing! What else is there. Could it be sonething with the fuel canister? Any sensors that might tell it to quit? Is the computer junk? Please help
