Thread: MAF Questions

I have not fully researched the topic but my limited knowledge on the subject has suggested to me that 10P engines only have MAF for EGR.

If you delete EGR you don't need it.

Later 15P's use MAF for fueling.

I have noticed that with MAF disconnected that first accelerate after starting there is no power for about 3 seconds. It then kicks in and is fine until next key off.

I will see if the new MAF fixes this.

New MAF must fix this unless it's a circuit issue on that path albeit it's quite unlikely cos then disconneting the sensor should not make much difference, when the ECU detects a fault after ignition it needs few seconds to switch to the default mode that's the delay you noticed, part of the so called addaptive strategy.
