2002 bonneville se trans surged or lurched stalled once

[dkc]

Ok i have a 2002 bonneville se with 155,000 miles on it just bought it about a month ago .I have put about 2500 miles on it since
with no problems so far .I did flush out all the dex cool and change the thermostat to a moto rad 195 deg unit, the top of the motor
is spotless no leaks of any kind oil is clean uses no coolent .Now the problem is after driveing about 70 miles today i was siting
in traffic at a light the car kind of lurched then stalled (never did this before ) it started right back up and ran fine .I drove the car to a few more places and during that time the trans felt like it would lurch or jerk now and then it never stalled again and only did this
at low speed driving inner city 35 mph or less anybody have any ideas on this.

As a test, try disconnecting the MAF sensor and see if that makes a difference. We seem to be having a rash of failures of those lately.

yep, my Buick kept doing the same thing recently, turned out to be the MAF.

Well i have been driving with the maf dissconnected for a day and a half with no stalling i let everybody know if it starts
stalling when i plug it back in.

Well i drove the car around for a few days with the MAF unplugged with out any problems .Saturday i plugged the MAF back in
and had the jerking right away tonight sunday night it stalled at a red light started right back up . well i guess its time for a new MAF
thanks for the replys i would have never thought the MAF would cause this issue.
