Hi,
I have a 1987 Honda civic si, 1500 . The idle control valve has failed, and no amount of cleaning or adjusting with keep the PGM light from going on , or stop the idle surges.

I need a new or expertly rebuilt idle control valve /FITV. I've tried 3 junk yard parts, and each is worse than my current part.

Does anyone have an answer to this problem?
This is a discontinued part. Nobody sells or manufactures it.

I believe you could buy a newer FITV ( don't know which model or year)
Part and take out the seals, and ceramic float and put them into the body of the old part. Does anyone have any info on this idea?

Also, it's been suggested it might be possible to find a newer throttle body that fits this 87 motor - but I don't know if that's possible, or if so- what model/year Throttle body might fit.

Any answers & suggestions are appreciated.
