WJ 4.7 - hard starts when the engine is warm
I'm having hard time starting the engine when it's warm. It starts easily when the agent is cold (First morning start) and when it's hot.
But, when I let it seat for couple of hours, it starts only after couple of seconds of turning the starter. When it starts, it struggles to rev for one or two seconds, then it stabilizes on the idle RPM and runs fine. If you put your foot on the gas gently in the correct timing, it starts quicker.
I'm not an expert, but to me it sounds like the engine is flooded.
I did some reading on similar problems, here's what I checked so far:
1. There are no error codes (By turning the ignition switch on three times).
2. Priming the engine by turning the ignition switch on and off before attempting to start doesn't help.
3. Gas mileage is 11.5 MPG. Almost of the drivers are 5-10 miles long, so I think it's not usual.
