I have a 98 Honda Civic with 160k miles. She has problems on a cold start. It sounds like she is misfiring, but when I give it gas after a while it clears up and I'll be good to go. I've replaced spark plugs, spark wires, distributor cap and rotor, fuel pump, fuel filter, and map sensor. I also cleaned up the fuel injectors with seafoam through a vacuum line and Lucas in the gas tank. I also have a check engine light for a crankshaft sensor. Could this make it misfire on cold start?

 

First focus on fixing this^ issue. There are two different crankshaft sensors -- one inside the distributor (CKP) and one behind the crankshaft pulley (CKF). What is the specific CEL code?
