Sounds like you need a new throttle body to be honest. I really do not believe it is your wiring. If it was the wiring it would not start at all not get any fuel. The pulse heads may be bad in the TBI this would cause them to over inject fuel. Now if your wires got burnt due to a fire due to this problem you may need to replace some. I would try a new TBI though before buying wires.

wiring harness.....possible but unlikely............did you say you replaced the on board computer?...........is it a rebuilt?......is it the correct unit for your vehicle?.........have your computer checked to original manufacture specification,s........then have your engine temperature sensor checked [not the one for your Gage...the one that report,s to your o,b,c........it,s responsible for your cold start mixture.].....next check the throttle body itself......may need rebuilding/replacing.
