1990 trooper running bad when motor is cold
when i first start the trooper on a cold motor it runs bad until the water temp starts to warm up it will only run about 500rpm and sputters and when you try to drive it it will almost die when shifting to 2nd gear and some times when you stop it will idle up and down between 1200 and 1800rpm. but when the motor is completely warm it runs fine with no problems and just want to fix the running bad because it is aggravating
