Lately, my Rio has been a bit slow to start. It takes about five times cranking before it catches and runs. NEVER have a problem once it is running, and never have a problem when the engine is already warm. Just cold start. Fuel filter changed about 5000 miles ago. New coil pack, air filter, and plugs (10k miles). Maybe the fuel injectors? There is no CEL coming on. Any thoughts? Many thanks

New wires? What did you gap your plugs at?
