What Next?
My car will not start unless I spray gas in the TPI air intake, and then it will run but idle rough, and the fuel pump flow is good. 
In help is good. thanks

Re: What Next?
if you have a fuel injector light noid. you can check to see if the pulse is good. I recently replaced my distributor due to the pickup disintegrating. I know the fuel injectors also get the info from the distributor.

Re: What Next?
You could have a bad injector, or an ECM going out on you. The ignition module is also a possibility but they usually lose spark before they quit working the fuel, and they make the fuel pump run so I would doubt that's your issue.

Re: What Next?
I had this same problem with my 86 IROC when I bought it. I replaced the IAC and TPS and the problem was gone. Let me guess: Throttle response is also terrible?
