hey, how is everyone, haven't been on for a while but to make a long story short......my friend blew his motor in his 95 civic ex, so we swapped it with another of the same kind the d15 vtec.......we got it in no problem, but the thing wont idle for sh*t.......runs fine in top-end but coming to a slow it runs like crap......the only code it is showing is code 22, two long and two short flashes on the dash....and thats vtec pressure solenoid? any help would be appreciated......i tried adjusting the idle and no luck

 

you checked the IACV? Not clogged?

 

yes we checked that.......i tightened the throttle cable and it idles alot better....i didnt put it on so i was just assuming it was tight....gonna go test drive it before it gets dark. hopefully that was the problem

 

took it for a ride and it still doesnt idle right.....it will idle fine then it drops down to almost nothing and feels like its gonna die.....then it revs back up on it own and its fine till it does it again after another 10-15seconds

 

ivac cleaned.......any ideas?

 

Did you swap the throttle body too, or just the motor?

Example: auto throttle body on stick motor??

Coolant bled through the throttle body??

Connections correct around the coolant sensor area?

 

definatly make sure your coolant is bled.

 

four words...Fast Idle Thermo Valve...

 

we swap the whole intake manifold with it so the throttle body is the right one.
so what is the fast idle thermo valve?

 

What about all the sensors and actuators? Were all those swapped along with the whole engine or did you keep the old ones and move them over? Its possible its just an engine management issue, could be a bad map, o2, IAT sensors, or possibly a bad fuel injector. Make sure everything is plugged in, Also make sure the each injector harness is plugged into the correct injector, i've cought a friend's own idling problem with a harness swapped across the wrong injectors after he did some work.

Sometimes it could turn out to be a big problem, or it could be a very ez simple issue, it can be easy to overlook simple things, i've made that mistake in the past.
