    Default 1993 Century Stalling

    93 Century 3.3 is shutting off while rolling, no issues when in park idling or giving it gas really. New battery from this summer with a full tuneup and just replaced the alternator for good measure and the problem is still persisting. Starts right back up with no issues, any ideas where to go from here? Thanks.

    Do you get any trouble codes with the check engine light?

    Does it just shut off like a switch especially after it warms up? Then I?d be looking at the crank sensor and ignition module.

    Or does is start stumbling until it finally stalls? Then I?d be looking at fuel pump, filter, and maybe injectors.

    No engine light and havent tried to pull codes, its pretty cold so progress is slow. It shuts off regardless of having warmed up or not, the conditions for it to stall just seem to be when its in drive and barely moving, when idling in park or driving everything is fine.

    Idle air control valve sticking? I?ve gotta clean out the one in my Celebrity every year.
