Random Stalling...
This is strange. Awhile ago I had the dreaded Code 41. Replaced the magnet no more stalling.
However, sometimes when I start the car it will idle down real low to like 400-500rpms, then pick up. As im going down the road, the RPMs will keep "bumping" down to the 500rpm range, and my headlights will dim as well, almost like its losing electricity. Now it is stalling going down the road when I start to slow down. No errors, no engine light, nothing, just stalls. It usually does this when it has been driven, then stopped, then started again. It never seems to do it when the car sits all night then its started in the AM cold.
For the record, fuel filter and pump were replaced, as well as some lines. Since there is no code, I have no idea why it'* doing this. Could it be MAF or TPS related?
Thanks.

everything dimming could be because the rpm'* are slowing down turning the alt slower.
If its a direct stall then restarts with no codes it could be the crank sensor or a dirty or loose connector at the ICM. also check and clean all underhood grounds at the Batt and on the fenders.
