I got a cold air intake installed today as well as a new magnaflow muffler. They both sound and wwork great! The only problem is that now my crx blows black smoke on acceleration. I know black smoke is usually unburned fuel correct? How do I fix this???

 

this is a EF forum for 88-91 civics.

you should post you questions here for pre 88 civics. Classic Hondas - Honda-Tech

or in the engine forum Engine Machining & Assembly - Honda-Tech

 

Sorry. New to this. I will do that

 

I'd say run it for a bit, the ecu needs to adjust for the cold intake
