2003 ZO6 Missing Running Rough
I was on my way to work never over 30 mph pulled up to a stop sign and the care died, when i cranked it back up it was running really rough like it was missing. The car only has 33000 miles on it. I replaced the fuel filter, MAP sensor, coils, plugs and wires and it is still running rough and missing. Definitely not burning all the fuel being injected into the cylinders. And stinks when i crank it. I am out of my depth on what to do. Is there a better scanner I can buy to hook to the car rather than using the DIC because there are no codes other than some door codes that pop up. The car was running perfect and suddenly terrible.

Welcome to the Forum !!...Looks like you started firing the parts canon already !!... and if it stinks like that it’s probably running a little rich but without a scan tool we can’t be sure without looking at fuel trims . Sounds like a dirty air filter or MAF...don’t like making a diagnosis based on symptoms but that’s a place you can start !!
