Could be the EGR. My car was spitting out this code for the longest time after I had changed the O2, etc. Blocked off the EGR the other day and my CE light went off...

If it thinks its running lean yet you smell raw fuel then the most likely culprit are dead O2 sensors.

Thank you i changed the air filter and oil checked for vac leaks and when i ran codes again i got nothing seems to be running better i checked again and still just showing 111 oil presser gage seems to be at a different spot every time i start the car sometimes on the M in the middel and sometimes on the N of normal never shows danger but wondering if it was bad gage or sending unit or pump and would the code reader pick up any of those problems thanks for any help Rob

It might take a while to relearn to the rich condition if you cleared the codes. The funky gauge sounds like a grounding issue.
