I looked in back articles and found only PaulsHighPerformance to carry these. Is that true? It seems as if they aren't availible there anymore but I haven't called yet. Does anyone know where the best one are still sold. Maybe some aluminum ones? I am haveing the hardest time finding information on them and where to buy.

Mine need to be replaced because under wide open it sometimes just falls on its face due to the runners closing. Please help!

If you have Aluminum IMRC's (only seen a few plastic ones over the years), then pull yours out, remove the blades, remove the shaft & have the ends welded up. Simple, easy & dirt cheap.
Done it tons of times...
You'll have to run springs on the throttle ends to keep the computer from throwing an error code. There must be resistance on the throttle linkages in order for the computer to still think the IMRC plates are working. Or, have a chip put in that has the IMRC function deleted.

Expect ~10ft/lbs of torque loss below 3500rpm on an N/A motor.

Thank you.
I have a 98 so mine are plastic. I have a spare set in which last night I took completely apart and will be jb welding the holes up to make it function.

Now on the check engine light, I already have it coming on saying that bank 1 side of IMRC has an error. So I currently have one side acting up. I just want to eliminate them completely but don't want the code coming on. There isn't a plug in device similer to MIL eliminators for exhaust that can be plugged in the original harness to trick the computer? If not, is a chip the only way to prevent it? I'm not sure how you would hook up a resistance spring to that after removal.

Depends on what is broken. If the plates themselves are stuck closed, then simply putting springs on the ends of the throttle linkages will prevent an error code. If it's the computer itself (mounted under the intake), then you'll need to use a chip/flasher to turn off the IMRC function....thereby eliminating any error codes.

Even on 98's I've found aluminum IMRC plates.

What I typically did as well was smooth out the ports in the IMRC plates with a sanding roll & die grinder. I'd also use a punch to remove the bearings on either end on the plates.
