I just replaced my air filter in my 94 940 with a K&N. In the process I disconnected the air mass meter harness so I could move the top half of the air box out of the way. Immediatey after I installed the new air filter (and replugged-in the AMM harness) the idle became a little bit rougher and in the next couple of days countinued to worsen. At this point the car occasionally dies at idle. The idle is rough, but in a pulsing or surging kind of way thats very consistent. I feel like the problem is in the AMM area because after starting the car, I've unplugged the AMM harness and plugged it back in, and the idle smoothens out for a while. Anyone have any input as to what might have happenned here? I'm going to clean the harness and amm connection and gob on some fresh dielectric grease and see if that helps.
