Engine Performance problem
2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 10000 miles
I have a 2000 Blazer that runs great when there is no moisture in the air or if it is not raining. But when its raining it wants to hesitate, but once it gets warmed up good or sits in the sun for awhile it will run fine. We have spent a ton of money and are tapped out trying to find the problem.
Could this be something electrical. Have replaced plug wires, plugs, fuel pump, pvc valve, rotor cap, and several other things. Please help I need my truck.
