My 1990 Dodge B250 van starts fine then quickly revs itself up to 2500 to 3000 RPM. (In the winter months this doesn't happen, the engine just floods itself, stalls, and will not start again for 30 to 45 mins.)
I asked a mechanic who suggested the coolant temp sensor is faulty and it's telling the computer the engine is stone cold, even at normal operating temperature. As a result the computer is calling for massive amounts of fuel which it is dumping down the throttle body.
I checked the fault codes and got the following:
12- Power Fail (no big deal)
22- Coolant sensor out of range
33- Standard code for vehicle w/o air conditioning (so I'm told)
41- Alternator field control circuit open or shorted (I don't understand this one)
46- Battery voltage too high during charging, or system voltage too low ( Once again, I don't understand this one either. I have not observed any electrical issues at all)
A friend says a bad MAP sensor will cause this?? HELP!!
