Hi:
Lately my fuel economy numbers have not been good at all, so I was trying to look at some of the basic items. I did some searches on the forums on how to test the MAF sensor. This is what I have done so far.
Test #1 - Unplugged the MAF and drove it, car was a bit more responsive right away while keeping the same driving pattern.
Test #2 -
a. With MAF unplugged and car warmed up fully, in neutral, floored the gas pedal, RPM gauge was able to cross the 50 mark in the red line zone. Then shut off the engine, and did test b.
b. Plugged in the MAF, in neutral, floored the gas pedal, RPM gauge was able to reach the 46 mark, just above the first red line, was not able to reach the red line zone.
Test #3 - Requires a VCDS scan. Can someone please help me with this? I am in the East end (Scarborough) and work in Markham, so can meet up around there. I believe this test would be the most conclusive.
Questions -
1. Are these signs of a bad MAF?
2. Is it OK to drive for some time with the MAF unplugged till I source out a replacement?
Thanks in advance.
