Re: hesitates, jurks or stops at times when slowing or stoping or starting out
There should be a relatively constant frequency output at a given RPM and throttle opening. If the signal goes to zero Hz (or nearly zero) would indicate an open circuit. The MAF is reasonably easy to remove and inspect, but is not an inexpensive replacement item. Unfortunately, you may be discovering that the hard way. Many of us have been there.
It might also be helpful to monitor the reference voltage at the MAF sensor to determine whether that falls off as well. That could indicate a wiring problem.
