I have a 02 Caravan with a 3.3 Flex Fuel, I get the codes P0107 (map sensor voltage low) and P0108 (map sensor voltage high). I have replaced the map sensor, then the Throttle position sensor, the air filter. I placed a jumper on the map sensor plug from supply to service and the engine adjusted to the voltage. Once I removed it the engine idled back down. I have checked all vacuum lines and could not find a leak, I checked all wires in the system for breaks and tested them, when I pull a vacuum line the engine revs up, and when I place it back the engine revs down. I noticed I had bad Spark plug wires and even changed the spark plugs and wires. Once you get it to idle it will idle fine, no noise or knocking, if i push the gas slowly the engine will start running rough and jerks, But if i push the gas fast the engine does fine till i stabilize the throttle. anyone know what this could be?
