i have a 91 explorer that had no power at all so i took it to the shop. he fixed lots of problems but the big one has stumped him. When ever you accelerate it jumps into open loop and floods the engine like it's cold, but when its at a constant speed it will stay in closed loop. he found that there was an updated module to fix the oposite problem and with no other options he put that in. now the PCM is saying that it has a bad reading from the camshaft position sensor. It doesn't have a CPS. from what i understand this is because the california cars always had CPS's. Is there a place to get the updated module with out a california stuff (he couldn't find one) or does he have to put a CPS in. If he does have to put it in does that mean a whole new wiring harness. Any information i could pass on to him would be greatly appreciated, it's been in for 8 weeks and both of us really want it out of there.
