91 Olds Silhouette, 3.1 V6. On start, hot or cold, the engine stumbles @ 400 rpm and dies. Restart and goose the gas pedal and it catches and idles @ 1500 rpm, dropping to 900 rpm after about 30 seconds. Put it in gear it runs fine. Plugs & wires replaced this summer. Cap & rotor replaced in '09.
What do think I should check? I am guessing the thermac intake system has a component either stuck or sticking. I will try spraying some PB blaster on the damper in the snorkel.
Any suggestions/ideas? Thanks.
