  1. OK I am calling this problem fixed (been a week with no issues). It was the Vacuum controller (also called vacuum control valve/manifold) mentioned in an earlier post by I believe rockfangd and also BBF (Thanks for that). My vacuum has gone from a very erratic 10-20hg to a steady 23 hg. Its interesting at startup and idle it is only about 13-15 hg other then that it is a pretty solid 22-23 hg (at stop lights and what not). This tells me the vacuum canister must be doing its job. Here is a link to rockauto of the part I replaced http://www.rockauto.com/en/parts/acd...rol+valve,7036 . Once you do your basic troubleshooting to verify Vacuum lines are OK and if you are still having a problem I would strongly suggest replacing this valve as it seems to be somewhat common problem, doesn't cost too much and is very easy to replace. To replace it all you have to do is take the passenger hush panel down, reach up and unlatch the valve, remove the vacuum line assembly (unplug it), reverse for the install (had no idea it was so simple until I did it as it sounded like a horrible job to replace :-). I did remove the glove box (also easy) and would probably suggest you do that just so you can see better, I also borrowed the wife's hand mirror (with a base and swivel) so I didn't have to stand on my head to see under the dash. The hardest part was getting the little spring clips off that holds the vacuum block on to the valve (still no big deal). If you do have this problem and you want to troubleshoot I would strongly suggest you get a mighty vac, they run under 50 bucks and it can double as a vacuum gauge. I put my mighty vac in line with the vacuum actuator that controls the flow between the face vents and defroster (also easy to do, the line is under the driver side hush panel) and ran it that way for a few weeks, every time I had the problem the vacuum would drop to 0, then after a few minutes it would bounce back until the next time it failed. If you decide to use a mighty vac this way be sure it is not in direct sun as I laid mine on the dash (in July heat in Austin TX) and I think it blew a gasket as it kind of jammed up, I did get it warranted though. I can't believe I have been living with this problem so long with such an easy fix. Anyone else like me and rely way too much on these forums for answers :-) . Before the net I use to just go after problems until they were fixed, now it seems I have to find the problem on the net first and get answers before I tackle them. I guess I figure if I can't find the answer in the forums it must more work then I want to complete. LOL The interesting thing is I found a lot of post with this problem but very few that provided definite answers and hardly any that pointed to this vacuum valve. Hope this helps others. Thanks again!

  2. It sounds like you have all the nuts removed - there should be only two anchor points per side. Is it possible the seat brackets are rusted to the floor panel?
