Found the diagnostic port under the dash above the gas pedal, jumped pins 4 & 9 to get the CEL to flash the codes and I get the following:



I see the code for 14, which is the IACV(just replaced it with a generic from O'Rielly and it lasted about 2 hrs before wiggin out again) but the second one is 11 long flashes and 9 quick ones? Or am I really that stoned and I'm missing something?

 

Update- So I ended up filing in some slots to unscrew the 5-points on the IAC valve and took it apart for a thorough cleaning. Performs as well as the generic which I returned. Plugged everything back in and the car runs great until I rev it past 2k and then it surges between 1K and 1500 at idle for an hour, and then the IACV totally goes out. Same result as if you unplug the IACV while its at idle. Engine revs to 1500 and the mixture smells really wrong. These same codes reappear. Its an '03 cls and I don't have an obdII reader which leaves me the paperclip trick. If I reset the engine light, the problem with the IACV resets as well. Runs fine, then the alternate revving, then the 1500 and stinky air/gas mix. The generic did the same, but it happened quicker.
