Runs rough and no power,light comes on at idle only any amount of rpm will shut light off but still runs rough. what could cause this?
SOURCE: rough idle stalls at low rpm's
hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck
SOURCE: runs rough
How long have you had this problem? It could just be a bad tank of gas. Other things to check:
1. fuel pump and filter
Could be running on only 5 cylinders due to
2. spark plugs/wires
3. plugged fuel injector
Any problems with electrical? Like lights dimming at same time as running rough?
4. could be bad alternator putting excessive load on engine.
SOURCE: 2001 v6 escape rough idle when cold
To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).
The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.
My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.
