anyone?

CEL lightg came on again only at start up. Car started but takes longer to crank. Car reumbles into cold start and the RPM meter drips and bounces and feels like it's missing a cylinder and then the |CEL came on. Car runs fine but when stopped..at idle..the car's rpm dips like 50-100 rpm or so every so oftern.
