Good thinking. I will try the gap change. I had wondered if the coil pack could affect these two cyl's? I checked it's resistance and it seemed ok, however I noticed something I have never seen before, when I put a timing light on the wires going to the affected cyl's the timing light would flutter eratically, whereas on cyl 1 it was steady and rhythmic. Something else that I have seen on other postings - and have not done yet - is a valve adjustment. but it seems doubtful that both are tight. Thanks for your input, Robert

Thanks for your input Adrian, I did a visual inspection of the mass air flow sensor - and it seemed in good shape. The reason I discounted it being the source of the problem is two-fold, 1: If it were faulty it would set a code, and 2: I would think it would affect all 4 cyls ? Robert.

I have a 96 subaru legacy wagon problem that has me and some mechanics stumped. There is a loss of power under load - when accelerating up a hill - and I get the code for misfire in cyl 2 & 3. The short term fuel trim goes way up when this happens. I have checked fuel pressure. It has new wires and plugs, a new knock sensor ( in my hunting for the cause, it was found to be kaput.) Also tested manifold vacuum, indicated no blockage in exhaust, and did a compression test which turned out to be fine. If anyone can help me, direct me, I would be very grateful.:-\
