My 1993 240 wagon has begun to occasionally stutter at stoplights, usually after I've driven about 6 blocks after a cold start. After this stuttering, which feels as though it might die if I don't give it a bit of gas, it often accelerates jerkily, almost an on/off pattern. I'll push the pedal down and sluggish response for 2 sec. then revs up for a few sec., then back to weird sluggish mode. The car totally died a few weeks ago and I discovered that the output tube of the air mass meter was disconnected. Reconnected, it runs mostly fine except issue #1. I think the first condition predates the AMM problem, and still persists. Could they be related? Otherwise, what are other likely culprits for this type of behavior? The fuel pumps, and filter are quite new, I have verified the fuel relay seems good. Though the plugs and wires are pretty new, and the plugs don't look excessively dirty. Any thoughts?

I plan on cleaning the throttle body this weekend, and thoroughly checking for vacuum leaks. I'm wondering what else I could check.

I've been reading this board intensely for a couple days and would really appreciate any feed back.

thanks!
