Hello. I have a 97 Plymouth Grand Voyager SE with 197,000 miles. Recently the service engine soon light started coming on and the van started stalling at idle. I took it to a dealer and they couldnt find anything wrong with it except Map Sensor/ Baro which I already had replaced. I also had it at a Chevron Service Dept and they also could not figure out the problem. I can drive down the interstate and the Service Engine light will go out and the van will run fine then at any time the light might come back on and start the van stalling. Does anyone know what else might be causing this problem? The engine is the
3.3 Litre and the van is the SE with the MK III kit.Thanks in advance.
Jeff
