Thanks for the kind welcome and all of the help as well! My idle problem appears to be solved! Yesterday I calibrated the TPS, cleaned the IACV and installed the new O2 sensor. The idle is aabout 600rpm, a major improvement over the 1300rpm before the repairs. I'll find out next week how well she performs on the highway and I'll post an update as well as keep track in the garage. Before getting the VX 'd change oil and filters on my cars, now I think I'll take more repairs on in the future... at least on the VX. My Subaru has a lot more going on under the hood and I find that more intimidating. I love the simplicity of the VX engine compartment. Anyone know of a good Subaru repair site I can bookmark? Thanks again to everyone, I could not have done it without your help.
Maybe your car also have vacuum leak like mine. Read my thread under general tech title "Paid SVOboy a visit" for more info on that theory.
I'll check it out. My problems aren't all gone. Idle is better, but still can't decide if it wants ~600 to ~1000rpm. I suspect a vacuum leak but can't find it, even went through 2 cans of starting fluid trying like heck to track it down. Thanks for the heads up.
I spent a lot of time chasing a similar problem on my 89 Honda Wagon. It ended up being the IACV valve was leaking a little air, when the valve was not energized and it was supposed to be closed. If you take off the valve, you should not be able to blow through the valve, with it not connected to anything. If you can, then you need to get a replacement.
Its a 92 and from what I read the vtec-e thing wasn't on there til 94 & 95, but I could be wrong. The engine block is properly stamped and all the parts seem to fit a VX including the 5 wire O2 sensor. I ran through this in a different thread. See http://www.gassavers.org/showthread.php?t=5149
Thanks though, I appreciate the comps! I think she's a real gem. I'll be real happy once I straighten the FE out. If I can get 50 I'll be happy. It's running on the wrong plugs now and I'm changing them tomorrow. I'm hoping plugs will help.
It looks like a vx engine.. Like mine - 93 VX.
My paint is also faded like yours. I need to repaint it.
