Hello im new to the forums here and need some help.
I have a 2006 volvo xc90 2.5T that has a rough idle it gives me 3 codes P0101: mass or volume air flow circuit range/ performance, P2112: throttle actuator control system stuck closed, and P0170 : fuel trim bank 1. when i first start up the car it runs fine after a bit it starts idling really bad like it wants to die and eventually it does. Checked all the plugs, coils, did a quick check for leaks and found nothing the MAF was recently replaced by the po. poured some injector cleaner in the fuel and it helped a bit but then started acting up again, maybe the fuel injectors need more cleaning? or something with the throttle body? any input would help. thank you

 

Hi carlosr9200 I was wondering if you resolved the problem and what the fix was? I have a '04 with similar issues and I have replaced the mass air flow sensor, which helped, but not completely.

Thanks
