pcm intermittantly switching van into limp in mode
Bought this van used in "as is" condition. I figured given the shape it was in and the fairly low miles, I might get a couple years before any problems arise. THREE DAYS AFTER PURCHASE - engine comes on without any warning. Shifting into gear the van wanted to lunge whereas before it was silky smooth. I have a code reader and was getting PO700 and PO755 which indicated a transmission problem. I can tell you, this thing didn't have a tranny problem. I was able to reset the code and the van was fine for a while. Seemed every time I would let it sit overnight, it would return and go to 'limp in' mode. No forward gear other than 2nd. Clearly this limits your speed dramatically. I replaced the solenoid pack, speed sensors and a wiring connector. Also changed the transmission fluid and the van worked again! For four days... I gave in. Brought it to an auto electronics specialist. They determined the PCM needed replaced. Also stated the one in the van now is a replacement. This will cost me about $2000 when all is said and done. I don't blame the dealer as really these are usually auction cars and I've bought from him before. This limp in mode is an utter joke. Let me burn up the car if I want. What's worse than going 40mph with your engine revs at 4k?
