I got a 93 honda civic 2 dr hatchback. I just did a swap and the engine is running abnormally. It's revving high as well. I checked everything and someone told me it might be the pcv valve. Does anyone know if it could be the pcv valve and how do i know if its bad and where can i locate it on my civic.

 

I had a bad PCV valve once but the engine was kinda running like it wanted to die not high revving. you might wanna check the throttle linkage or whatever it is you tweak on the throttle body itself. sorry i couldnt help too much
