I was thinking of that. Does it actually work? Also I was about to post about the Vacuum hoses on the TB that goes to thermostat housing we dont need those either right. I took out my heater & A/C & no longer have the core or nothing So i'm going to block off all of the coolant lines & bypass the TB see any problems. I dont think there are.

Funny. I bought the piece of aluminum from Home Depot and cut it to fit. The hardest part was getting the old bolts out.

Yeah. I had some aluminum laying around.
Tools needed for removal: Phillips screwdriver, hammer, vice grips,WD-40,
12 pack , band -aids, & patience. Them things are a b**ch.
If all else fails break out with the Air Compressor( I almost had to)

I don't have AC so that isn't a problem. You really need the ISC if you have AC. It idles too rich when the car is cold so you have to keep your foot on the gas a tad bit to let more air in. Not a big deal. Within 1 minute, it idles perfectly.

With a VPC, it actually idles better like this. Another pro is I don't have those coolant hoses running to the throttle body heating things up.

Does this eliminate the FIAV aswell?

Or has anyone just filled the passages for the FIAV with high-temp epoxy? If so, will the car maintain an idle without the FIAV?

trying to avoid replacing the TB due to a bad FIAV...

That entire section where that valve was is gone on my t-body. Idle is fine. You can always block off the FIAV and still use the ISC. Just remove that piece like I did and you'll see what I mean.

Just wanted to ask if you were able to reuse the bolts/screws you took out or if you got some to replace them? If so what kind?

I never saw this thread but I did it to my throttle body as well. Works fine. Not for pansies who can't handle a changing idle depending on engine conditions...

i bought my car w/ the ISC disconnected. now that the weather is getting colder here in colorado its becoming more annoying to have done but its still not a problem if i let the car sit for a few minutes.

does anyone w/ their ISC disconnected experience a loss in RPMs if they rev the car up a tad, like say to 2000rpms, and keep the pedal still? when i do that, and the car is still cold, it will drop from 2000 to like 600 and feel like its about to stall, then pick back up and be fine after that. just wonderin if anyone else noticed it.

when my isc blew and ruined my ecu, i made a block off plate. i have recently seen problems with my coolent temp raising and bumping down timing. i don't think it was caused by removal of the fiav and bypassing the lines, but you never know. also, i'm worried that i might have a leak coming from the plate, but thats my error, and won't happen if done correctly. my car stalls sometimes when dropping from higher rpms and when i'm turning [power steering], but i don't know if the stalling problem is from the isc or a bad mas. anyways, its another great way to eliminate wires and shit from under the hood...

fabbing a plate is too much work, however, is reversible. Bare tb's are cheap, so I did this to a NT 91-94 tb.







the liquid steel was later smoothed out. New tb seals, idles like a champ.
