Question

I just moved from Florida to Indiana. My 94 formula ran great in Florida but after it got to Indiana, via trailer, it is running like it is misfiring. I changed plug wires today and it didnt help. Any ideas?

Optional Information

Answer

I believe your car is equipped with a MAP sensor. This takes a reading of the surrounding atmospheric pressure. I would say the pressure is different in Indiana than it was in Florida due to the elevation. Disconnect the battery for 10 minutes. Reconnect battery and turn key on for 30 seconds, then turn key off. After that start the vehicle, but don not touch the gas. Let it idle for 2-3 minutes and take it for a drive. This will give it a chance to relearn the baseline value for the MAP.
