I have a automatic 2004 gmc envoy with a 4200 vortex motor. I'm having a bad idol problem and misfires, the car will also stall and die completely every now and then and will take about 20 minutes to get it started back up. I've changed the spark plugs, engine coils, and cleaned the fuel injectors and the car runs fine and then BOOM, the check engine light comes on and it has the same problem. Any idea what is going on??
It also has 190,000 miles on it
