Plugged catalyst or low fuel pressure can do that.

Thanks I'm thinking it's the cat converter then, going to check it first

When was the fuel filter last changed?

Check engine light on? Might be a misfire that clogged the cats? Clean the throttle body and IAC? Test the TPS?

Not sure when fuel filter was last changed. Bought car about a month ago from mechanic shop. Said it sat for about 6months then driven several times as shop car. Ran great until rattling noise underneath about a week ago. Thanks for trying to help

Hi I own the t-bird and after letting car sit all morning I just went out and it fired right up and revs up as normal. Didn't drive it yet. Does this sound normal? Maybe all the rain and moisture for some reason?

It could have had something wet in the ignition system that has dried out.

1992 Ford thunderbird V8 Turns over, but it will not start. New fuel pump, fuel filter fine, fire at plugs and cord. new plugs and plug wires. any suggestions
