My car starts right up but dies. If I keep my foot on the gas it will stay running but not smooth. I've replaced the cam sensor, crank sensor and fuel pump.
I still have the same problem. Could it be the TPS?

I've checked for vacuum leaks. The check engine light comes on. Code 77 speed control Relay circuit. I was told that was nothing to do with my problem but I checked relay and it is fine. So I replaced ht IAC and the problem is fixed! I love this site.
