In hindsight I've had a bit of a miss on some cold starts lately (the weather has also gotten much cooler), but something went bad wrong today. It was pretty cool this morning, about freezing. Started missing as soon as I started it, I figured it would clear out in a minute or two, it normally does. Instead of getting better it got worse and started smoking (gray). You could smell the cats. Nursed it back home smoking and missing, read the codes, cleared the codes, uninstalled the Cobb, now it won't start. Codes were:
29AAF - "normal" fuel pump code for a lot of Cobb people
2C3D - O2 sensor code
2C7B - O2 sensor code
2C7B - O2 sensor code
29CD - ignition miss
29F1 - another fuel pump code
I assume the O2 sensor codes are from all the missing and raw fuel. I assume that any sort of fuel pump failure would result in lean problems rather than raw fuel problems...anyone disagree? This is the first time I've seen a bunch of gray smoke from it. I can see how it could possibly be ignition or an injector stuck open, but the problem would appear to be on more than one cylinder from the way it's running and the amount of smoke being produced.
Anybody seen this before?
