Cel code 42

[ssblackbullit]

So after draining all the bad gas and refilling with fresh premium and installing a new filter I am getting the cel code 42 and it's running like chit. I've read that the code is relatd to the ignition module or the coil pick up. Anyone wanna give some advice on what to look for. I was gonna take the ign. Module off and have it tested.

Will this cause it to run poorly? It idles fine and doesn't stumble while in park. When in drive, it stumbles and almost stalls when accelerating past 1000 rpm.

Yep. Think it was the plug on the pass side. It appeared to be pretty corroded. I cleaned it and now no code. Runs much better. Thanks again Dave.
