I recently adjusted my valves on my 91 camaro rs 3.1 and once i got it all back together and started it up it will idle at 500 and then and 100 and then at 2.5k. what do you think the problem would be. and how do you suggest on fixing it

Vacuum

Doc here:pimp:

Check vacuum, it should be a steady 17-20 in hg..(if no lumpy cam) If it bounces, re adjust your valves, you have one or more slightly tight.

Does it stall/backfire on throttle?
