Maintenance/Repairs

See previous discussions cali emissions thread on my 02 Suzuki XLZ 4WD. It has 149,000 miles, has had a new starter, new fuel pump and lines, and new brakes in the past year. Bought it a couple of weeks ago and took it straight to shop, so I have no personal history with this car.

Now: have replaced all catalytic converters and exhaust pipe. Have also replaced Mass Air Flow Sensor. Great news - all computer codes are cleared. Runs great when in park or neutral (30 min or more). Mechanics then moved it around parking lot with no problem, so they trusted it enough to take it on a test drive on the open road. Made it out of sight of shop (not sure how far, but it was an improvement over the last time!)…but required tow back. Hooked back up to diagnostic computer, and found NO error codes. They are doing what they call “exploratory surgery” (yikes). Am I wrong in thinking this is probably a TPS issue? What are the other things that could cause this inconsistent power/stalling when it is put in gear?
