1999 Mitsubishi Galant Q&A
1999 Mitsubishi Galant Question: I have a 99 galant which has an rpm needle problem.
I just had my timing belt and crankshaft sensor replaced. Car runs fine but once i turn on the heater the cars rpm/idle needle starts moving uncontrollably and the car start to misfire by shaking and not wanting to accellerate. The check engine light also goes on but i had the light check and it says it needs a tuneup which i already did with new parts. I dont know what to do. - omarmendez9
you need to resolve the light issue which is telling you about a missfire. start with a compression test to see if there is any valve damage. Roy - mastertech6371
I want to make sure I understand.....the engine misfires only when you turn on the heater?......or the misfire becomes worst when you turn on the heat? - BroadwayAuto
