Brake booster vacuum hose, let it suck it up a little at a time.

Ok I'm curious. What's the point of the seafoam thru the pcv system and the brake booster vacuum?

It runs the chemical thru the same path as the so if there is any carbon build up or fuel "gunk" it will brake it down and flush it out. The bottle in the fuel tank doesnt do as much cuz if you're already running premium fuel and driving daily the gas does a pretty good job of keeping the fuel system clean.

Sorry meant to write same path as the air.

Well I replaced the IAC valve, the PCV valve, sprayed out the MAF, ran sea foam thru the intake and unhooked the battery for 30 min to reset the computer and it barely made a difference. The rpms still pop up a little when I press in the clutch and when I'm coasting at 35 the rpms are hovering around 1100. I'm giving up, I decided my car just has chronic retarded idle.

You can remove the annoying "hovering" rpm-crap by making a custom gasket with smaller holes in the top and bottom.

There are instructions out there on the interwebz, I have seen them, but haven't done anything with it yet.

Personally I find it to be extremely annoying most of the time...

So to answer your question... No, I tuner can't help with this.
THIS is what I was referring to above. I hate to link to another forum, but that is where the info is at for the custom gasket that cures the high RPM between shifts......

Yeah and I thought that, but when I got the replacement part it came with a gasket that had smaller holes than the gasket that was on there, I thought that would take care of it. So now I guess I gotta try that gasket thing

Re: You guys with tuners

I hope the gasket got you straight.
Not to ask a stupid question intentionally, but did you verify that nothing odd at all is going on with the throttle cable, spring and linkage on the throttle body getting caught up, or the clutch pressure plate not re-engaging immediately after letting off the clutch cable? You get what I mean & what I'm thinking about? I'm not sure but real curious to learn when you get it straight. Good luck.

No even with the new gasket with the smaller holes I'm still have the problem. The throttle body and linkages all look good, I rotated the butterfly a couple times and snapped right back to the RPM adjust screw.

Re: You guys with tuners

Put the stock IAC gasket back in place until you get this figured out. There is no sense in having a new variable to deal with while you are troubleshooting this mess...

K I threw it away but I think I can dig it out, but when I first put the valve on I left the old gasket on and drive home. Noticing that it didn't make a change, I then put the new one on seeing little change.

I just cleaned my tb iac valve and my maf and it's not doing it anymore. Could have carbon built up in it.

Re: You guys with tuners

Good deal, glad to hear it.
We need to help Kingmidas87 get things straight now. When I am stuck on something similar mechanical, I call the Mustang shop and talk it out with them and hold a pen and paper in my hands. They always seem to "have the way of the force" and know. We use Excessive Motorsport, Manassas Va. in this area:FYI

My 95 has a smaller gasket than the one I seen pictured on that forum and looks like the same diameter
