Have they checked your TPS sensor as this is the most common cause for rough idles and stalls...

you might also want to check the timing on your engine. it's not unusual for these motors to skip a notch & your intake & exhaust valves will be out of order.
Hello
The engine
and transmission in this cars drive train are fully
electronically controlled by a computer called the PCM (Power Train
Control Module). Whenever a problem like this occurs the computer
stores a record of the problem (there are of course some exceptions
to this, like the fuel pump, engine coolant temperature sensor and
MAF sensor for instance) in the form of a fault code in its memory,
to read these fault codes you must have the systems memory scanned
with a special tool. Once the fault code(s) are read you then must
perform the appropriate diagnostic testing to find and resolve the
problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN
HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON
PARTS THAT MAY NOT CORRECT THE PROBLEM
