Can anyone tell me what the symptoms are for a faulty maf sensor,
99 UK Turbo

 

try search, but....

rough idle
hesitation/pulsing under acceleration
increased activity on a knocklink display (if fitted)

what symptoms are you getting?

 

Idle seems fine,
If i am sitting at 1/12 - 2k revs in 1st or 2nd gear sometimes feels like it is pulsing as you say, but no hesitation on acceleration.
Don't have a KL.
Is the MAF located on the down pipe, have purchased a H&S centre section and BB
considering a decat D/P, will there be a port for the MAF.

 

Will there be a port fort the MAF on the decat down pipe

 

MAF is Mass Air Sensor so its in the air box

Lambda sensor is in the downpipe.

H&S downpipes have the threaded hole for replacing the lambda sensor.

No, the MAF is in the air flow into the engine and is after the air filter.



It's the Oxygen (aka O2/Lambda) sensor that's in the downpipe as MB has pointed out.

I have instructions on how to change the MAF on my website if you need to.
