1990 Chevrolet K1500 Cheyenne 5.0L Poor Idle Quality, Hesitation, Surge, Stall
What other items need to be changed or added to get this motor to idle properly on start up and eliminate a slight hesitation on the road? Owner wanted to increase size due to lack of power and age of previous engine. This engine runs great except for the item...
