1997 Ford Ranger, 150,000 miles. When it's 50 or colder outside, once the truck is warm, the engine will surge or buck while idling, unless I give it a little gas. Check engine light is on (has been for over a year) with the same two code, lean fuel and transmission, yet no one can seem to find the problem. Have had the O2 sensor, fuel injector, all kinds of other sensors, etc, replaced, but nothing, other than the weather warming up, seems to help. In the summer, the truck runs just fine, although the check engine light stays on, even after the codes have been read and reset. Then today, an especially cold and windy day, started the truckand the check engine light was flashing. This is new. Any ideas on how to fix all of this. I don't mind braking with my left foot to give gas with the right, but I also don't want the truck to totally die on me. ANY help would be GREATLY appreciated!
