been through hell since i've bought the car trying to come to the root of me CEL coming on. After reading a few other posts i know the car goes into limpmode each time.

airbox mod & DV were only mods then everything went to crap. ran a o2 sensor code - wasn't 100% but still had them replace it.

had cylinder #3 misfire code come on a few days later so I did the coilpack + spark plugs. Just for the record they are AC Delco iridiums...was a sunday and had 1 place open. ****?

now i'm throwing codes in 1,3,4 AND "says system too lean"...this coming from one of those blue scanners, says audi in colored font - small, upper corner.

At first i was pretty set that it mightve been the ects but realized tonight that looks like a green plug down there
