  • 2000 Taurus P1237 trouble code
    24 valve V6 will stumble or stall, check engine light comes on. Will restart OK and be OK for a couple of days. Replaced fuel filter and reset code and it was OK for 2+ weeks. P1237 fuel pump secondary circuit, fuel pump driver module. Anybody have experience with this one?...
