Your are half way there. My first guess is faulty throttle position sensor TPS. If this not telling the PCM that the throttle has closed when you take your foot off the gas it cannot in turn call on the idle air control valve to set the idle correctly. First I would make sure everything is spotless. Remove the air trunking to the throttle body and with plenty of kitchen paper towels and WD40 open the throttle plate and give the whole interior of the throttle body a thorough clean. Clean the Idle air control valve and associated passages too. So far this will cost you some time. The TPS is basically a rheostat like the volume control on a radio. There is a carbon track with 0 to 5 volts along its length and the contact position corresponds to the throttle shaft rotation. Before just buying a new one I would investigate if it can be repaired. First plug and unplug the electrical connector a few times to freshen the contact. Clean the carbon track with electrical (no residue) spray. Move the mount position of the middle contact along the throttle shaft a fraction; this will cause the contact to run on a less worn arc of the carbon track.

What is the safest Removal and cleaning of egr valve on a 1999 lincoln continental?


Doubtful. The EGR valve only opens when you are going 40+ m.p.h. and not accelerating. The EGR valve is normally CLOSED at idle and, when it does not seat correctly, it usually just causes the vehicle to idle rough. If it becomes stuck open, it will invariably cause your CHECK ENGINE light to come on (there is a position sensor).
You can use regular penetrating oil (WD-40) to clean and lubricate the EGR valve and see if that helps, but a more likely suspect is your THROTTLE POSITION SENSOR or your IDLE AIR CONTROLLER.

Idle speed too low


Sounds like you may have an issue with your idle air control or your mass air flow sensor. The IAC can cause a vehicle to stall when up to temperature, especially when warmer outside.I would clean or replace that for starters.

1999 for escort zx2 stulls when im at a stop light


Engine stalling and rough run issue at low speeds

This problem 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

The car runs then when you get to stop light it shuts down then you can start it just when the rpm is low it shuts off


The most common problem with stalling due to low rpms is the idle air control valve. this valve is what controls the idle and keeps the engine at the correct idle this is the first thing i would check and also make sure the throtlebody is clean, most of these type of problems are due to that valve good luck.

1997 Camry - Possible Fuel Pump??


this is a dirty idle air control valve, clean it using the following procedure.
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
