A little more info. The car kind of kicks and bucks lightly when at stop lights, it idles alright. I thought maybe the exhaust was clogged but after clearing both cats the sysmtoms are the same. It also slows down quickly when I remove my foot from the throttle, and then it lurch's when I again accelerate. Any kind of quick acceleration or a hill and the car runs horribly. And finally when I down shift into 2nd and remove my foot from the throttle it has a rather pronounced lurch. Any ideas would be greatly appreciated.

Ok going to revive this thread,,, Where to begin, well this problem has still got me stumped!!! Since my last post I've tried to replace the MAF, Swapped all 4 injectors, swapped the TPS, and cleared both Cats(sounds really bad now!!). The only time the car seems OK is on flat ground at about 2000 rpm. My question, What would the symptoms of a bad fuel pump be? And how can I test it? Also, has anybody been to Smart Subaru in Seattle? I'm just getting tired of throwing money at this thing!!!!!

Thanks for the reply, I guess I left a few thing out! No the CEL is not on, and there are not any codes. It seems to run this way intermittently no matter what the elevation or slope of the road, Its just that it consistently runs this way on my drive home, the road out to my place goes from about 600 ft to 1200 ft in 6 miles. I dropped it with a subaru mechanic near me, he's located near sea level, he drove the car and could find nothing wrong. The car seemed to run great at that elevation. The car kind of starts sounding a little rougher at first, then at times will sound really rough and has a general lack of power. It idles just fine when its running this way. I thought it might be some kind of exhaust leak, but the mechanic did'nt think it would be intermittent like this or affected by elevation. I'm really at a loss, its hard to get any kind of diagnosis on such an intermittent problem.

Hi all, This is my first post here, I've lurked for a bit! I recently bought a 92 legacy L AWD, its been giving me a headache. I've been having an intermittent problem for a couple weeks now. It seems to run fine sometimes and other times it runs rough, with a lack of power. The only thing I've noticed is that it seems to always run bad on long gradual uphill grades(on the way home). It seems to run better at lower elevations but starts running worse as I head home. I've replaced: Plugs & Wires v-power, oem wires fuel filter alternater rebuilt battery air filter oem pcv valve This has got me stumped. Any ideas? I've brought it down to Valley Subaru Service in Auburn, but the car runs great down in the valley!!! Thanks in advance.
