First off, THANKS FOR NEW BOARD!!
Anyway, I've been troubleshooting the torque converter lockup on my 1999 Tahoe. When hooking up my scanner (no codes, BTW), I noticed the MAF live data is 0.0 lbs/min.
Does anyone here know why?
I removed the MAF unit and cleaned it, replaced it and checked all vacuum hoses and electrical connections, and the scanner still reads 0.0.
Is this a problem?
Thanks in advance!
