I bought a 2000 Mercury Sable about a year ago. During the winter the check engine light came on and I had it read. It was running lean. When it was cold outside and the engine had not warmed up yet the car would stall and die unless I held the rpms around 1500 or so until it was reaching normal running temperature. I was expecting the problem to go away with the warmer weather, and it no longer stalls and dies, but when the car is at idle (stop sign, light, parked, etc.) or when the rpms are low and the load greater (driving slowly up a steep hill) the car will feel like it wants to stall and will making a jerking feeling from the engine area. Today while on the way somewhere, I was stopped at a stop light and it was making the jerking feeling more than usual (maybe every 3-5 seconds), when I took off from the stop light the car did not have as much power and the check engine light started blinking. I slowed down and looked for a place to turn around and go home. The problem didn't occur again and I turned it back on later to let it idle and it's not jerking any more than it usually would at idle (maybe every 15-30 seconds it will do it once).
Typically, it runs just fine as long as the engine is over 1200 or so rpms. I never have any problems driving on the highway for example. Any help would be appreciated, thanks!
