1999 Chevrolet Express 1500 Q&A
1999 Chevrolet Express 1500 Question: my engine starts missing badly after it warms up.
Items I've replaced : Crank position sensor neutral safety switch ignition module fuel filter fuel pump ignition coil no code is being displayed , some times the check engine light comes on then the motor will miss fire and the light goes out , it normally happens at about 60 mph any advice would be great. - gphvac
