Bad Injector

[rizzlebizzle]

I was plowing today and noticed that if I stomped on it I would get some white smoke coming out of the tailpipe. It would occasionally turn black. If I slowly worked the truck up to high RPM (like a highway ramp) I wouldn't get anything. Mulling this over I remembered about three months ago I got a CEL for a misfire. I stupidly cleared it and waited for it to come on again, not bothering to do any research. Now I realize I most definitely have a bad injector, and have had one for the past three months, probably longer than that. It would explain the hard starts I've been having. I need my truck for a snowstorm Tues/Wed and am not sure any garages are going to be able to give me a new injector on Monday.

It's made it through two storms already, what are the chances of it making through a third? Anybody else drive around with a bad injector this long and did it flood the cylinder and bend a rod? Eight new injectors are pretty much out of the question money-wise, will replacing one be ok or a whole bank instead of the eight? Anybody know a good performance shop in Southwest CT?

Update: I checked the fuel bowl for crud and it was super clean, not a thing in it to possibly clog an injector. I added half a gallon of gray bottle diesel kleen to about 7 gallons of fuel and burned up most of it highway driving. I saw no smoke, noticed nothing out of the ordinary. Only thing eventful was the truck overheating because the plow was keeping air from getting to the grille. It was about 25 degrees warmer here then it was when I noticed the smoke. Maybe it was a combination of crappy winter mix fuel and the fact that it was 15 degrees that caused the smoke? The truck had been running for about 6 hours straight Saturday morning when I noticed it. There is no coolant loss, no loss of oil pressure.
