Son let his car run out of gas, and when he filled it this code appeared with rough idle and stalling code 2002


I had a something similar to this happen to a girlfriend of mine. She has a 98 escort and it ran out of gas and the service engine soon light came on after she filled it up. If this is what your talking about check your owners manual. Most of the time if there is really nothing wrong with car you can drive it around ( Generally 20 min in town and 10 on the hwy with 4 idle periods (4 times of the engine being at idle) - do not cut engine off) and the light will go off. The rough idle code most likely happened when the engine ran roughly because. it was running out of gas.

I bought a second car for utility use; B6000, 1994, p/u, standard trans. Only when starting and running when the engine is cold, it runs very rough and difficult to idle. At normal operating temperatures...


a coolant tempurature sensor will make it run to rich if it is bad. run rough at idle, and produce black smoke, engine may stall out. it also causes retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage. good-luck!! if light is on check for problem code. this will guide you in the right direction. if no scanner, any auto parts store will scan for free. repost if need be. have a good day!!

Check engine light on; Gas milage went from 19 to 15, emission ba


YES!!, you had it tuned, it runs good, but gas mileage dropped, and check engine light is on,it sounds like the o2 sensors are slow or even dead, i would replace them for sure and that just might solve all your problems,good luck, hope this helps.

vacuum leak. Fords are not known for good gas milage though. 14mpg would be a likely use if running good

I have a 2001 Ford Escort. It was idling rough and starting to cut out when sitting at stop lights. I changed the plugs and within a week the Check Engine light came on. It is still idling rough but not...


Well the misfire in Cylinder 3 will commonly be that your plug has gone bad. If that is the only code that it is throwing out then it could be an array of things going on. It sounds though that you may have a throttle position sensor out or that you have your idle speed set too low. You will still have great response when gas is applied but sitting at lights the idle will be rough and sometimes bounce up and down.

Running rough, no power misfiring


i had that problem once. when i got under half a tank of gas in the tank. What i did was i dumped one bottle of gas line deicer in the tank and i have never had it agian. you may have some water in the tank. from condasation or i have a stong feeling i got my water from the gas station. i was using the same station all the time. so i tryed another gas station and so far no more rough idleing which was caused by the water i think and i am getting better fuel milage to. i hope this helps.

1998 Toyota Corolla poor gas milage


first i would change the fuel filter. this is the number one reason for poor gas milage. the engine tries to compansate for the lack of fuel and in the long run this weakens your fuel pump and it will fail sooner rather than later. i als would check the air filter. if the engine can't breath properly it will lose power. if you have not had a tune up I would suggest getting one. this most certainly help boost the performance of your vehicle. i would try and use an additive in your fuel to clean the injectors clogged injectors will make the engine run rough and cause hard starting and rough idle.. the last thing i would have you check is the throttle positon sensor and the O2 sensor. take it to a shop and have them hook a diagnostic scan tool to it this will show if either of these sensors are bad or if they threw a code and the computer is trying to overcompensate for the lack of fuel. hope these options help you. please rate this solution thanks
