Question about 2004 Ford F150
Engine will stall while driving w/ ac on but will restart . seems to be ok w/ ac off . i have had injectors cleaned but within 20 min engine stalled again.
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).
