XL7 rough running problems.
Posted: Fri Apr 12, 2019 11:47 am
Hi.
I’m after some advice regarding the problems with my 2005 XL7 petrol auto.
Was running great, now blowing black smoke, stalling etc.
Common fault codes are P0121, P0172 and P0175.
Checked MAF sensor, Air idle control valve and Throttle position sensor with a multi meter and all within range.
However, unplug the MAF sensor and it runs fine apart from running slightly rich, harsh gear changes and does not change into 5th gear, which I can live with temporarily.
Any assistance would be appreciated as I think it’s a great vehicle but I need reliability.
Does anyone know where I can purchase a MAF sensor as a starting point?
Regards, Phil.
