Question about Cars & Trucks
We changed the plugs, plug boots, fuel filters, cleaned the gas tank,n and blew out the fuel lines. problem still exists
Your changing parts why,for what reason?
You have to do some testing to determine the
area that is causing the problem,eg ignition,vacuum
Unless you have experience & factory diagnostic
manuals for your car, your wasting your time
It would be faster & possibly cheaper to have a repair
shop check it out

Check to make sure the Security light in dash on right hand corner is not on. If it is on , your passlock is enabled. to dissable it turn your key on but not start it and wait for apx 10-15 minutes. this should re-set it.

try this procedure and let me know if it cures the problem.
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.

I have same/similar problem.... if this problem happens off and on... runs well one day and next day is jerky-stalling then it's more than likely your airflow meter
