high idle upon start, then falls and hunts. AMM? 200 1991

posted by  someone claiming to be townes on  Thu Dec 30 22:23 CST 2010 [RELATED]

So on Christmas Eve my wife's 91 240 started acting up as we drove home.
We recently had the fuel pump changed due to failure. The car ran fine after but exhibited hard starting in the rain and when cold. We'd have to crank the starter holding it and pump the gas until it would eventually start, run rough, then smooth out after a couple of minutes and be fine. This time it just started running very rough and almost stalled repeatedly.
We took it to our mechanic and 220- later we had a new O2 sensor and a car that still runs poorly.
It starts up now when cold right away, idles high for about 20 seconds and then the idle slows and hunts and seems like it's going to stall.
If I unplug the AMM it will start and run steady but a bit rough. The last time I plugged the AMM back in and restarted the idle stayed high and did not drop.
Tomorrow I will inspect for vacuum leaks and clean connections.
Also, when I changed the air filter last night the air breather box was loaded with almonds and dog treats that somehow made their way from the inside of the car to the air box.
Any help would be GREATLY appreciated.

thanks, Kirk S.
