I've just had my car (RB5) mapped this evening.

All went spot on, but on my way home I noticed the idling was eratic. It was fine during the mapping process.

I immediately thought it was the maff sensor so I limped it back home.

I have done the CEL check but the cel light just constantly flashes which I believe is no faults found.

Any ideas?

 

teh check light doesn't always show a maf fault, but also could be the idle control solenoid, needs to be cleaned out with brake cleaner to make sure.

 

I have done the CEL test again which has revealed the MAF is goosed.

Where to buy another?

 

Zen performance sell maf sensors.
