I tried posting this before but then didn't see it in the 900 summary. So here goes again.

Our trusty wagon with 150K mi has turned up a problem just in the last week. She stalled once while my son was driving; then fine for a week. Then, after sitting parked for several days, she started with difficulty, and then wouldn't stay running without a foot on the pedal forcing the idle above about 2K RPM. She ran smoothly for a while, but after a stop for gasoline, ran along the highway with surging (ie., intermittent power drops). Engine light came on and stayed on. Around town, she starts and runs sometimes fine, sometimes roughly.

Pulled the code, a 1-1-3.

Do you think it's may be the O2 sensor (or connex?) Tried running some other diagnostics using the "A" module, per the FAQ, and some were fine but I didn't know how to run them all.

Any tips appreciated...am hoping not to strand my son or wife if they do use the car!
