1993 Buick Century
3.3L V6
~150,000 Miles
My fiance has a 1993 Buick Century. She took it to a shop to get a bunch of odds and ends fixed. Afterwards, and I believe unrelated the car started stalling. Typically this seems to happen when she is slowing down or at a stop. It will usually start right back up (although yesterday it took a few minutes). She also said that it sometimes seems like it is lurching forward. She took it back to the autoshop and they ended up replacing the spark plugs and cabling. It continued to stall. Then the disabled the solenoid valve in the transmission (something like that, disabling may not be the correct word). Still stalls. The car is always 'hot' when it stalls. At one point she mentioned that it seems to do it more when it is hotter. Yesterday, it stalled as she was backing out of my driveway (she wasn't there for that long though). I am planning on going to a new mechanic that was recommended to me but I would like to get a better idea of what the problem may be or if its even worth fixing.
Thanks in advance!

These kinds of problems are the hardest things to diagnose; if the thing were to stall and not restart right away, it would give the tech a fighting chance to catch the gremlin that might be causing this issue.
Things that it could be; MAF (Mass Air Flow) sensor, crankshaft position sensor, ignition module, fuel pump, fuel pump relay, the ECM (computer) and the list could go on for quite a bit more. About the only way a tech will find this, is if he was lucky enough to have a lab scope connected to whatever is causing this while it failed.
If I had to make a guess it would be a toss-up between the MAF or crankshaft sensor???

I'd go with the idle air control motor. Clean that thing up!

I would have to go with Dan's 2 choices.
The crank being the 1st along with inspecting the ckp sensor harness going to the module. That year was good for shorting.....
