I have a check engine light on and I read the codes with a scanner. The scanner read P2180 and P2178: system too rich off idle bank one and two, P2192 and P2194: system too rich @ higher load bank one and two, P0103: Mass or volume air flow circuit high input. Does anyone have any ideas? Does this sound like a mass airflow sensor failure? Thanks

 

Either a bad MAF or a big vacuum leak.

 

If it were a big vacuum leak, wouldn't the car run pretty rough all the time? The car actually runs fine most of the time. I reset all the codes and the car drives normally for a while with no cel. But, upon start-up in the morning the idle can be somewhat erratic until it warms up.

 

Not always sometimes it will only leak under boost.
The plastic pipes on the top of the motor are known to crack.

 

Thanks, I'll give it a look.

 

Alot of times one person has to be inside with it in gear and foot on the brake and press the gas till the motor goes into boost. Then feel around the piping for leaks.
