I have a manuel 94 civic lx four door that had a d16 swap out from a d15.. I've been having an idle problem with it. I cleaned the IACV and checked other things. Also when I turn the A/C on it bogs down the rpms and almost stalls out.. I've read things online about the condenser fan. From what I've seen the fan for the radiator works but not the condenser fan. I can use the A/C when I'm driving but not when its in neutral, parked or at a stop light in gear. I'm not as concerned about the A/C as I am about the idle problem itself. When at night and I have the lights on it also bogs down the rpms. It'll stall it out unless I give it gas to prevent it and this is only with the light not the A/C at night. I have the rpms set to around 800 to a 1000 at idle. I'd rather figure the problem out then just setting the idle higher. Idk if its an electrical problem or the A/C could effect the whole electrical system itself. Let me know if anyone can help, thank you.

Also when I have the A/C on when parked in neutral it'll make a knocking sound and bog down the motor. The lights just drop the idle down to below 500. Even when I put up or down the windows it'll drop the idle just a little bit.
