Hi, I'm new here. Decided to post because I have a 2000 Focus LX ( 2.0L 4-cyl. automatic) . It has 129,000 miles on it. Just replaced the motor mounts, and two days after I get it back from the shop it starts to stall as soon as I put it in park (can't even idle in park 3 seconds)
Sometimes the check engine light comes on, sometimes the battery light comes on.
I'm not sure if the mechanics bumped something or messed something up in replacing the motor mounts or if needing the mounts exacerbated the stress on some other parts.
I just replaced the mass air flow sensor around May of '11. Oil and oil filter were just changed two weeks before the motor mounts and air filter is < 2 yrs old.
I've been reading that it may be an oxygen sensor or a hole in a pcv valve. But one thing is irking me. Whenever I took it to the dealership last spring to replace the mass air flow sensor, the mechanic told me there was a small tear in a hose (didn't say which one) and that he put tape on it.
I also got a auto parts store to do a cheap diagnostic on it and he was unsure but asked me if my heat/ac fan (blower motor maybe?) was working. Something does smell like it's burning when the engine is warm and I turn the heat on. I realize the smell may not be related to the stalling...
Any ideas at all would be helpful. Thank you!

The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.
Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.
