My car idles high in park and i've changed the throttle positioning sensor and mass air flow sensor. I've checked the idle air control sensor and the fuel rail pressure sensor and they are good. My catalytic converter looks fine from the outside. My car idles at 2500 in park and neutral and now my intake manifold is glowing red hot. What do you think is wrong with it?
have the same problem?

Scn for codes adn check fulepressure first. It may be low orhigh. Clean tthrottle plate with choke cleaner on both sides an dcheck for a vacuum leak by spraying cleaner around ports, and connections
