Hello,
Now I have a new problem that started. Since it has been very cold in the mornings the car acts if it wants to stall out. After it has been warmed up it is okay. When I first start it the idle is very high like it is suppose to be. Then I put it in drive and it hesitates. I did not have this problem before the wire harness and ECU was replaced. It almost appars like the idle needs to be adjusted higher. The tach needle is sitting on the 5. I put white gas in the gas tank to get rid of water. Any other suggestions?
