Hi sorry if its posted in wrong section.
I recently bought my 2008 H3 and the check light was on...sometimes during ideal the rev started to play up then goes back to normal. it was diagnosed with P0102 code (Mass or volume Air flow circuit low). i was advised to change the Air flow sensor. i ordered new one, fitted it and they cleared the code....but unfortunately the check light popped up again and it sometimes plays up at ideal. i still use the car but want this issue sorted out. i was advised to check airflow wiring now. anyone else faced similar issues? what i need to do?

Your help would be highly appreciated.

Thanks

Try cleaning the throttle body.

 

The P0102 is for a MAF circuit voltage problem, has nothing to do with your idle being messed up. Separate issues. Make sure your air filter is dry and clean and check the wiring to the MAF for cracks etc.

Like chooch said, for the idle, start with a thorough TB cleaning. There are threads here an on line about how to do it, make sure to use TB cleaner and nothing else.

 

idle starts to play up sometimes.... i think it linked with the CEL and P0102 code. i will try cleaning the TB and check for cracks on MAF wiring. anything else to check for the P0102 code? Thanks
