SOURCE: engine cutting out when idling or slowing down

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

SOURCE: The rpm fluctuates at idle

It could be several things...low fuel pressure, a lazy 0 2 sensor, and even an IAC. If there isn't any service engine lights coming on, you will need a qualified tech to do the test since a lazy 0 2 sensor has to be looked at with some type of a volts meter and a scanner has the capability of doing a better job yet since you wouldn't have to get underneath the vehicle. Don't be fooled into thinking that it is just one thing; it could be several depending on the mileage.

Idle fluctuating rpm check engine light


run the fault codes as the engine idle is being affected by a faulty sensor . The vibrations are probably because the idle rpm's are too low.

2002 escape 3.0 idle fluctuates and misfires when driving


No such thing as a tune-up

All you did was replace spark plugs which should be
done every 3 years

Oxygen Sensors get replaced at 100,000 miles which you
also did

You most likely have an intake gasket leak,smoke test
the entire Evap System & Engine

You also are have bad igniton coils

Should the oil pressure gauge fluctuate with speed


The oil pressure guage will fluctuate with engine RPM. At idle it should be approximately 20 lbs./sq.in, at high revs about 50-60 lbs./sq.in. Hope this helps any concerns you may have. Good luck!

I am not familiar with this engine. But, if the alternator, PAS and AC are being driven by the same belt, then its possible that the belt is too slack, have you checked the belt tension ? That would be my first step. Hope that helps
