well.... my '94 accord ex Vtec DOHC seems to be pushing out ALOT of air... i took off the oil cap and put my hand over it and my hand was being pushed up while it was just idling?? Is this good bad or normal???? and i just put a CAI on it...oh, and i took it to the muffler shop and they put a new cat, pipe and muffler on it......

Now let's see if I can shed some light to a real answer to that problem..

I suspect a possiable IAC fault..(Idle Air Control) valve.
This valve changes the amount of air that will bypass to the intake manifold. This valve is activated by the ECU which tells it what to do.

When you put in your mods, did you disconnect your battery???
Another part that I believe could be faulty is your oil pressure switch, it could also be needing replacement if it is not working properly.

IAC will have no effect on that. Its normal. Thats why they have a PCV system. It is their to vent crankcase gas back into the intake.

The IAC would have an effect on the engines idle. And more than likely throw a DTC causing the CEL to come on.

And unless you have a swap.......you do not have a DOHC engine. SOHC only for the 4 cylinders in the US anyways.
