i just put my H22A into a 1994 accord EX-R
i used the F22B1 harness blah blah
it was running fine but i started driving it yesterday and now it runs fine under load but as soon as it comes back down to idle it surges about a thousand RPM for a minute then the idle cleans back up and runs normal

 

Which ECU are you using? I had a bad idle surge problem after my turbo install but it was because I was using a chipped civic ECU, which I was told would work fine. Once I switched to an LS ECU it was fine.

Is your idle like this?

edit: i reread your post and it sounds like yours is just one long surge, never mind.

 

getting any trouble codes?

 

ok update with that.....
on the driver side kind of beside the motor mount there is a valve with 2 vac lines going into it and an electrical plug
when it is unplugged it runs smooth but after load the idle still surges about a thousand RPM

but when its plugged in it doesnt surge but runs rough and sounds like severe misfire

ideas?

 

a pic might help
