1995 escort wagon 1.9 automatic, runs rough when I turn the deforst fan from off to on.
Just had injectors cleaned, I could not get it to run. took it to shop in Federal way. they said good spark, fuel pressure @ 40psi. Also the main connector for injector wire harness was not plugged in, they said they drove it and reported it rain good. I get in it to drive it home. I turned my fan on to defrost my windshield and the car began to run rough. if I turn the fan off it seems to run better. when at idle is when the car will chug like it wants to die. RPM's range from around 500 up to 900 bouncing up and down.
Usually the AC comes on when you select Defrost .. The AC condenses the moisture collecting when warm air meets cold glass
