Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????

Ok... using a digital ohmeter (if you don't have a scan tool) check the throttle position sensor, mass air flow sensor and the manifold pressure sensor (MAP). Instructions for testing are too long for me to write them out, but can be found in any decent repair manual. As a last resort, you can swap parts from another known good vehicle (maybe from a friend) this won't damage anything unless you break something during r&r. I'm leaning towards the tps, but on this electronic junk, everything feeds off of everything else and it's easy to get fooled... could even be the crank sensor. Sorry to be so vauge but without being there and driving/testing myself I can't honestly be positive enough for a definite answer. (you did change the fuel filter, right?)

SCAN YOUR CAR. HERE IS WHAT YOU DO. WITHOUT STARTING THE CAR, TURN THE KEY ON,OFF,ON,OFF,ON. WAIT SEVERAL SECONDS AND COUNT HOW MANY TIMES THE CHECK ENGINE LIGHT FLASHES.IT WILL GIVE YOU A 2 DIGIT CODE, AND IT WILL NEVER BE MORE THAN 7 FLASHES IN A ROW. RE. IF YHE LIGHT FLASHES ONCE PAUSE THEN TWICE THAT CODE IS 12. A CODE OF 5 5 MEANS THE SYSTEM IS FINISHED DIAGNOSING. PLEASE GET BACK TO ME WITH YOUR CODES. GOOD LUCK.

SOURCE: car starts fine, but stalls at stops and takeoffs occasionlly

Most likely it is running too ritch. should be around 7%. Mine did ecactly the same thing and I had several things done . Had the throttle body cleaned and installed a O2 senser.runs great now.

Hope this helps

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
