Fix your car

ONE OF THE COILS COULD BE GETTING HOT

ck. the tps(throttle pos. sensor)

Usually on idle (warm engine) this is OK.

if you dont know anything about cars then take it to a dealer as it will be cheaper in the long run

Check the gauge by holding in the trip odometer reset button and turn key to run,hold button for 10 seconds this will iniate a diagnostics on all the gauges,and lights if gauge doesn't move during this test replace gauge,if it does move then check the wires on the plug at the engine coolant temp sensor (ects) you can check the sensor by using a ohms meter by unpplugging it and check ohm's or resistance when cold and then start engine as the engine warms up the ohm's reading should gradually lower as the sensor is a thermister and as it warms up the resistance will drop.

sounds like u might have a sticking valve. i do know that they have had alot of valve problems with this motor

If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?

if there is not a vacuum leak it seems that the signal wire to the MAP is either open or shorted to 5 volt reference wire. if not either of those may be the PCM
