My 1996 mercury cougar xr7 is shutting off after I fire it up. It starts up and then idles down. Whats causing this to happen? I gap the spark plugs I sealed the intake manifold and the fuel injector gasket.

Scan for codes, check fuel pressure, clean throttle plate on both sides with choke cleaner, an dcheck for vacuum leaks.
