Vr6 Maf

[Rusty]

Be interested to know why this makes a difference, need to get Voltage for both MAFs and AFRs too...

Is there any more updates on this as my exhaust looks like im burning coal

Well update ...failed emmisions on MOT at idle ...only thing it is pointing to is VR6 MAF ...running rich

[quattrostyle]

okay thanks, that's good to know

running rich, im 100% sure the VR6 MAF makes the mixture lean, thats what my plugs would suggest anyways.. Although saying that, running rich on idle would explain why mine sometimes runs like a bag o'***** when im sat in traffic... Hmm interesting.......

Surely idle will adjust off the lambda probe so the MAF signal shouldn't cause rich or lean idle problems, even on fast idle the lambda should adjust the mixture. Be interesting if it is the MAF.

Thats a good point, i did have an intermittant lambda signal error come up on vagcom when it was last plugged in, ive got a new genuine one, ill get that on and report back if its solved the problem
