hey all,

i recently picked up a 99 2.5RS with an avo turbo kit strapped to it and it's throwing multiple CEL's that are preventing me from getting the car tagged due to emissions. here are the codes:

- P0446 - Evaporative Emission Control System Vent Control Circuit Malfunction
- P0103 - Mass or Volume Air Flow Circuit High Input
- P0101 - Mass or Volume Air Flow Circuit Range/Performance Problem
- P0220 - Throttle/Petal Position Sensor/Switch B Circuit Malfunction

The car seems to run fine...I just had the 60k mile maintenance done, which included a set of new plugs.

Any help would be greatly appreciated!

thanks in advance,
shu

could be you have some bad sensors.
