recently my crx has started jumping around a little bit at idle......it slows goes from 1000 to 1250 exactly about 5-10 times before going down to 500 rpms.......I don't think it is a vacuum leak.....my setup is an a6/z6 mini me converted to obd1 that throws a code 9 for no reason whatsoever.....but yeah any help would be great guys thanx

Does it only do this while the motor is still cold?

Could be a bad iacv, might want to check into that

 

mine does the same thing except i have no codes with my ls swap. help would be nice

 

Do a search for FITV and IACV. That should work. I had the problem before and it was the FITV.

 

I put this on my car and I love it, It is a voltage stabilizer, it helps a lot.

Look at my Battery

 

it mainly does it when it is warmed up and especially at night.......do those voltage things really work?
