Chaparral 243 Vortex Misfiring when cold

[tcutsone]

The port side engine misfires (Engine Code P0300 & P0302) when I first start the engine. After it warms up, it runs fine. The RPMs are off until misfiring clears. Any ideas for remedy?

Common codes. Put new plugs, check ignition coils and seat properly. Those would be the first steps.

Ok, thank you. I will give it a try.

Read the plugs when you change them...........plugs tell you a lot on the health of the engine and even the coils ect...............the plugs will also tell you which cyl/plug was having the misfire. Most times like Luc says it just a simple plug change.
