Thread: 454xl stalling

  1. #1

    Default "I have twin 1995 454xl fwc.

    "I have twin 1995 454xl fwc.
    idles great when cold, cruises fine, but when throttled back to idle starboard motor stalls within a minute or so.
    So far we have swapped or replaced every sensor and module, wires, distributor, fuel pump, and filters and nothing changes.
    I have read about this happening but cannot find the fix.
    Any help would be greatly appreciated.
    thanks,
    Dave"

    "Does 'swapped or replaced every sensor" include the ECT, MAP, TPS, KS and IAC?

    Did you check each sensor connection for corrosion as well as Vref and ground integrity?"
