I THINK IT THE FUEL SENSOR OR WHAT
Problem just started.Runs fine at high speeds,but stals out at low traffic speeds and stop lights.this only occurs when car has warmed up.Wish Iknew?????????????????????????????
It sounds like your IAC,idle air control,this unit controls your idle once your choke completally shuts off.on 2.8litre it is located right side of engine just above where your fuel lines go into your manifold ( fuel rails), it's held in by 2 screws &looks like a little electric motor, it's actually a soliniod, inside is a little pinnacle that goes in and out and is controled by the computer.good luck.

is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control
Autozone and similar stores will check the codes in the computer for free usually. That is the best place to start. Other possibilities are Engine Coolant Temperature sensor (saying the engine is cold when it's not) or excessive fuel pressure (bad regulator or blocked return line)
replace all vac lines first , then you need to get someone to run fuel pump pressure test to be sure you are getting proper fuel pressure , then take o propane torch ( not lit of course and go around all vac lines and intake with motor running and see if motor speeds up when you are holding it next to any suspected vac leak the tranny in this mod shifts off electric solenoids check to be sure all battery connections are clean and that i wire that ground the motor off the battery is in good condition and clean and tight , however the main care should be to vacuum and fuel pressure
try this ok trun the key on let the fuel pump run do this a few times.on the fuel rail there a black cap on it becareful not to smook put a rag around itbut where u can see the valvepush it in.or u a gage if it see realy low.or fuel dose not shoot out and spary all over. then it the dieaphram on the fuel rail that control fuse if stuck closed it will send fuel back to the tank
check to see if you can hear the fuel pump running.just cycle the key to the on position but dont turn over the motor you should hear a humming sound come from the fuel tank.if no sound check your fuses if all ok could be a bad fuel pump
or check to see if you have spark if no spak then it could be the module inside your distributor cap.it also controls the fuel pump.
