I got a 93 CX with a b18b1 swap. When I go to start my car for the first time in the morning the car idles about 2.5k and then it drops to about 2k and just idles up and down. Its pretty annoying. Any ideas? I see no loose vaccum lines or leaks. TIA>

 

most likely your fitv. Its on the bottom of your throttle body. take it off witht he 3 i believe 10 mm? and pull off the coolant hose. at the end there is a plate held on by 2 phillips head screws. Once you get that off, inside you'll see a piston. Take a flat head and put it into the slot, and screw it back in as far as you can go. Now put it all back together and your done.

 

I will try that out.
