Help with Idle
I have a B20 swap in my 1997 civic and I've been having a horrible idle problem ever since the shop put it in and I cant figure it out. Its a constant surge like a vacuum leak, specially when its cold but once it gets hot it calms down but still surges a bit. It smells strongly like gas when I turn it on until it gets hot. I checked the timing, the intake manifold gasket, the PVC valve, I checked the MAP, The IAC valve, the ECU, I checked for vacuum leaks around the intake manifold but couldnt find any....Im out of ideas...anyone has any?

RE: Help with Idle
when you say it smells like gas, that reminds me of that coffee can, as we use to call it.
the canister - that is what it is.
sounds like a problem with that - but not real sure.
with that swap though, hard to tell.
take a spray bottle of water and spray around the intake at the engine.
see if you can detect a leak - or did you already do that?
i would probably replace all the vacuum hoses - cost 2 to 3 dollars. i did that.
did not replace the 2 big ones - off of the brake booster or off the iacv (or eacv).
should be able to look at them at tell if they are bad - those small hoses though, you cannot do that - at least i could not.
