Rough Idle

I have a 1995 3.8 thunderbird auto has new tune up plugs wires plugs new mass air too.What it is doing is at start up stumbling, missing and dying at idle just when you start it its fine after it warms up no codes either. Has anyone had this happen too them?

Thank you
Scott

Re: Rough Idle

Recommend cleaning the throttle body, paying particular attention to the IAC. If, after cleaning the IAC, the problem persists, test the IAC:

Re: Rough Idle

There's some Throttle Body and Air-Intake Cleaner at parts stores.
