Subaru Other

I have a 1990 subaru legacy wagon, 2.2 liters, 206K miles, that runs fine after I " feather" the throtle up to speed, but if I start up an incline, or try to speed up quickly, it sputters, pops, backfires, etc. If I force it to get going, it will race breifly, cut out, race again, then I back off and all is well again. Not sure when it was last serviced, just got it, and can't put a bunch of $$ into it right now. Thanks, Lee
