It could if the front bearing is locking up, this causes the belt to stop which in turn could cause the concern.

2003 Ford Explorer XLT Wants To Stall At Low Idle,, especially when at a stop light


How does it idle in park , does it run ruff or smooth? Are any lights lit on the dash , check engine etc. ? Could have a partially plugged IAC air passage .idle air control (IAC) valve ! The engine computer uses the IAC to control idle , when under a load such as when put into gear the computer raises the idle ! It does this by allowing more air to by pass the closed throttle into the engine raising the idle ! If these air passages clog they restrict the air flow an cause a idle problem !

2005 taurus ac problems


I would think more along the lines of the idle stepper motor or a bad vacume leak or airflow sensor or intake leak but I havn't seen the car. The A/C however does also control the idle it makes the idle higher when th A/C engages to cope with the load but if the A/C is off & yu expeirience the prob then I would sugest the A/C is not to blame. The A/C belt runs on the Idler & tensioner pully & I assume they were noisy & better to replace then have them seize & throw the belt which could cause other damage

Engine seems to lack power w/ ac on . now engine will stall


Check the RPM if it drops when you have the AC on while the car is not moving. If it does drop you may want to check on the idle compensator. Its job is to bring increase RPM to make up for the added load. You may also want to check on the idle if it is below the normal speed. The added load may decrease the speed and send you to stall. If they all check out OK, you may want to check out the compressor as well if it gives the engine too much load. This can be caused by a faulty compressor or too much freon, or the bearing may be bad (with the bearing, you will get to hear a screeching or whinning sound).

2003 Ford Taurus wants to die when coming to a stop


TRY THIS AND LET ME KNOW IF IT CORRECTS YOUR PROBLEM
Here is the most common cause of surges and stalls at stops and low erratic idle speed and 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
