Engine Performance problem
2000 Ford Focus 4 cyl Front Wheel Drive Automatic 104267 miles
i had the transmission rebuilt 3 months ago, ever since that my car idles rough off and on and has been stalling while driving not sure if it was caused by the new transmission, but when it stalls the car will restart and u can drive it for a while and it'll stall again, replaced the 02 sensor-fuel pump and filter has no air leaks and fairly new plugs and wires does need an oil change though gonna replace the coolant temperature sensor, but if that does not work then what could it be? It's a 2000 ford focus se 2.0 single cam has 104267 miles. Oh and you can let it idle for 3 hours and it'll stall as well.
