Subject:      Running poorly and I need some ideas
Content-Type: TEXT/PLAIN; charset=US-ASCII

Something I think I know just enough to be dangerous, but not enough to be helpful.

----- My van is doing the following and I need some ideas:

- lots of sputtering at idle. My van barely maintains idle and nearly dies.

- blackish smoke is coming out the tailpipe (its not super thick, but it is certainly noticable).

- I can hear some "knocking" noises in the engine. Not sure what this is but there is a distinct knock-knock-knock noise.

- I think I hear valve clatter that is different from the above knocking (but I'm not 100% sure I know what valve clatter is).

- When driving down the road, it surges a bit, but not so bad I can't go.

---------- Here is what I have done (some of these probably don't matter, but I'm trying to be complete)

- adjusted the valves. Some of them felt very soft. After starting up and hearing even more valve clatter, I readusted the valves and tightened the "soft" ones even more. This seemed to help both the valve clatter and the van seemed to run better, but it was still bad.

- checked the timing. It seems ok, but its hard to tell with poor running at idle.

- new plugs, cap, rotor today.

- new air filter.

--------

Help! Any ideas? Thanks, Blake SLC, UT 84 Westy
