It dies when im at stop lights or signs, if it doesnt die it sounds very rough getting back up to speed. The check engine light is on and has been since i bought it, it has new oil change and i just change the transmission fluid today. Wen i bought it the man said it had new breaks and tires, but it is very bad on loose gravel and rain, could this is the quailty of the tires? it has 201,500 miles on it. I bought it at 197,000. it is a turbo.

Without more info it might be hard to figure this one out. I would start by replacing the Idle Air Solenoid. Also check to see if the EGR valve is open.

I had 2 experiences like that. 72 ford pickup I was watching it try to run after I got home from work. It was dark and I could see sparks. I also noticed the coil was very hot. I changed to coil and all was well. I had a 94 sunbird it ran good at high speeds but I could not keep it running at a stop sign or stop light. I change the plug wires. I had not code. I suggest you check the code if you have a check engine/warning light. It can help narrow your search.
I don't even remember if the 72 had codes back then but I have learned to check them any time I have a check engine light.

SOUND LIKE FAULTY IDLE SPEED CONTROL OR EGR VALVE.HAVE VECHICLE HOOK TO CODE SCANNER TO LOOK FOR TROUBLE CODES.

sounds like a fuel problem either a dirt blockage or the computor is mailfuctioning

start with a tune up, (air filter ,spark plugs, plug wires ext)..adjust carborater(air fuel mixture could be off)

Check the intake manifold gaskets for a vacuum leak.

Have you tried cleaning the mass air flow sensor ? Use Qtip and carb cleaner to remove any gunk on the two wires that strech across the inside.

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk 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.

If it does turn over but won't start, check for fuel and spark, if not spark then check to see if the crank sensor is cover with dirt.....

This may be a pcm problem, but it really does sound like a fuel pump., except for the dash light issue. Your dealer is the best alternative at this point. They have all the tools and scanners that are specific to your vehicle. Probable only cost an hours diagnostic fee. Give them as much info as you can, and tell them what has already been done.
