Ok I want to regroup my thoughts here, because I am all over the place with this one. SO:
The issue: I will be driving down the road and the car will suddenly kill. Once it kills, it doesn't want to start back up.
Temporary solution: Disconnect the battery for a brief moment and reconnect it
Codes:
- P1860 TCC PWM Solenoid Circuit (Irrelevant)
- P0113 IAT Sensor 1 circuit high (Irrelevant)
- P0403 EGR Control circuit (Irrelevant)
- P0101 MAF Circuit range/performance <- I thought this was ruled out, but it wasn't.
- P0300 Random misfire (Irrelevant)
- P1554 Cruise control feedback circuit <- I thought this was ruled out, but it wasn't.
Things I have tried:
- PCM
- ICM
- Crank position sensor
- IAC
- MAF
- TPS
- Unplugging cruise control module
- Anything fuel delivery related has been ruled out
Things I plan to try:
- Searching for a shorted wire in the harness, since both P1860 and P1554 are in regards to electrical problems
- Ohming the injectors to make sure one is not low on impedance, causing the driver to overwork and overheat the ICM
Other interesting things:
- Boost/Vac gauge reads approx. 18 in.Hg and the aeroforce reads like 23?
- I have been driving it to work, and I don't know for sure if resetting the codes is the remedy (haven't been able to do a control experiment), but I can drive for an hour and so long as I reset the codes, the car will stay running. However, because I have been driving it to work, I have been disconnecting/reconnecting the battery before I head out, just to ensure I don't break down on the interstate.
Any other ideas?
