STALLS AT RED LIGHT OR STOPPING

My guess, throttle positioning sensor is failing and won't hold when it's hot. this sets base idle.

If you have the foot on the brake when stopping and it stalls , try slowing down and stopping on the hand brake to see if the engine stalls . If it doesn't stall on the hand brake then I would suspect a leak in the brake booster that is affecting the engine by letting air into the manifold through the activated booster. If there is no difference have the fault codes read as there may be a missing/ faulty vacuum line connected to a actuator in the gear box.

Change the gearbox oil and the auto transmission fluid it may be old and dirty so it slows down shifting.

YOU might find its due to the Auto Matic gear box as when you slow down at the lights or brake hard to stop the auto box should brake free at about 600rpm as to allow the car to stop but the engine to keep idling,but the drive bands in the gearbox and the pump which operate them are not braking free so its like, in a Manual g/box driving and stopping but leaving the clutch pedal and not pushing it in so the car stalls,
SO you may find that the next time you are driving it and come to the lights just try putting it in NEUTRAL gear before you stop and try, if it ok then get the g/box serviced . RON

oxygen sensor

fuel filter most likely

the lock up converter is staying engaged when you stop have it scanned for trans codes may need lock up selinoid (tcc) or torque converter changed try putting it in neutral before you stop if it stays running this is probibally your problem

does the rpm motor kick down? you may need to check your vacuum hoses, and also you may want to check your exaust, sounds wierd but that can cause the car to stall at times.as for the traction light, your hitting the brakes to hard. try slowing down a little slower while stopping, and keep distance for saftey.. if you can take it a little slower at lights and turns, without braking hard and it stops stalling.

Hello marquesevond ..

It may be related to the transmissions electronic control unit. The most common symptom would be that from a dead stop the vehicle feels like it starting out in high gear. The transmission computer or TCU (transmission control unit) suppose to control the automatic upshifts an downshifts but may not be downshifting the trans back to first gear. To verify if this is the problem try shifting the transmission like it was a manual shifted transmission. From a dead stop start off in 1st an manually shift. When slowing down, shift down manually just like it was a manual transmission. On a turn you should be in 2nd gear or 1st manually with your hand shifter depending on how fast you are going. If it drives and shifts good, without stalling, you may have a bad TCU to diagnose.

OK this is a very common problem. there is a 4 pin connector on the trans. (just below the air box area sometimes blue or grey)(in a shape of a box) that is your TCC soleniod switch connector. just dissconnect that and see what happens. if your problem stops then you need a TCC solenoid. what that does is it locks up your converter at 40mph+ or HWY speeds to save on gas. another way to test it is when your slowing down and it feels like your driving a stick shift and it wont get out of gear and stalls. if that is what is happing thats your problem. just dissconnect it if you want but i remomend getting it fixed. DO NOT REBUILD TRANS. many trans shops try and pull a rebuild on this.
