Hi all:

1985 245. I've been working on this car for 8(?) months+ with time out for lymes (I don't recommend it).
it's finally running but doesn't handle increased gas. Distributor rotation doesn't fix it. Fuel pressure is about 30 at the rail and doesn't drop on acceleration. There's soot in the exhaust. The Cat converter had disintegrated and was empty. There's a signal at the distributor. Both computers are replaced, there's a small 3rd one under the glove box but it looks new so I haven't messed with it. I found several air leaks but the change was minimal, a leak would have to be huge to have that much effect (judging by the effects of the small ones). The vacuum lines test, unless there's some I haven't found. The gas has been replaced but is still dark. I'd be grateful for any suggestions.
