Might be time for a new IACV.

Agreed, does sound like IACV. Try blocking it, and see if that solves the situation.

Can u eliminate the iacv all together or do I need it.I'll try and block it off and see if it gets better.Are all the b-series the same,iI think mine is off a 91.So do I use a piece of plastic to block it off.

No they are all different. You should get one from a b16. I just used a piece of cardboard to block it off. You can not eliminate it. The system has to have the IACV connected.

Because it is the closest to the a-series that has been found. You LS may work, but it is uncharted territory.

You should check out Google (http://www.google.com). For real man, TON of information about b16 motors.

So i talked to a guy at work who used to work at honda,he said to take the cover off the fitv and turn it out a turn.He said it shouldn't be turned in all the way,going to try this on the weekend.

The idle control system is described in detail on pp. 12-43 and following in the manual. Lots of troubleshooting info, etc. There is also a symptom chart on p. 12-40.
