running stupid rich after timing belt change??

[makaveli42]

timing belt was just changed less than 100 miles ago.. car made the 40 minute trip home with no issues. it sat for a few days and today it started putter about 2 miles down the road. CEL started flashing and then went solid. wideband was reading 7.4 at idle!! I turn it off and let it sit for a few. start it up and drive the 2 mile trip back home. cars blowing white smoke from the exhaust like crazy and smells like straight gas. wideband still reading mid 7s at idle and under throttle. I run the codes and get this...

any ideas? the shop doesn't open untl Monday. gonna have the car towed there then if I cant figure it out this weekend. i cleared the codes and started it up and its still the same...just haven't drove it to have the CEL kick back on...

I'm just not sure what they could have done during a timing belt, water pump, crank shaft seal job that would affect the fueling like that?

Fuel injector. Look for a pinched wire would be my guess. Not sure how it would have happened with the work list shown, but it is No. 1, which is right front.

Have you tried to drive it? Boost hose loose off an Intercooler? You've got fuel to match the air measured by the Mass Flow sensors but the air isn't getting into the engine?

Yeah ive checked all th boost hoses. I'm blown them off many many times. They give different codes and run different as well. I've never had a misfire code before. Having it towed to the shop that did th service tonight. Hopefully they figure it out soon after.
