    Age old stumble issue

    What are the chances timing could jump on startup on a car that's sat for awhile through the cold weather? I fired up my SL today and it seems to fall on it's face at about 5psi boost (Autometer A/F guage goes straight lean when it does this). WOT seems to cure the lean condition, but it just doesn't pull (it will make it to 10-12psi, but takes a long time to get there). It ran normally when parked (other than axles clicking/popping). No codes other than 12 & 55 (battery was disconnected).

    This is a Shelby Lancer, completely stock other than boost and A/F guages.

    That just happened to another forum member. He parked it, came outside and wouldn't start. Timing belt jumped.

    That was my thought, especially since the belt has been sitting in one position for a couple months and it's still cool enough that it may still be a little stiff. Thanks I'm not crazy.... or crazier heh..
