Recently purchased an '85 Subaru GL 2wd. There seem to be a few problems with the engine revs, namely:
1) On startup, I have to pump the gas to keep it from dying (if I don't, it will die every time on the first key turn but start ok on the second) and usually rev it at ~3K rpm for 1-2 minutes before I can drive. I know it's an old car but. . .
2) The idle seems high, although the previous owner may have just cranked it up due to the problem above. . .
3) I can be cruising the freeway in 5th gear and the revs will jump from 3K to 4.5K and stay that way for awhile, then jump back to 3K. I've seen it do it in other gears as well in other ranges (3-3.5K, then back, etc.)
Any thoughts? I checked the vaccuum lines and I know there are some minor problems there (i.e. - one of them has a golf tee plugging it) but I haven't been able to figure out where it should go yet from my Chilton's manual.
Thanks.
