2004 RX8 Hard to start sometimes
 
I have a 2004 RX8 with 50K miles. First crank up in the morning she starts fine (make take a second or two longer than it should). But after she warms up and you shut her off it becomes hard to start. I am fairly sure she is flooding. If I hold the gas pedal and crank a few times to unflood her she will finally catch. Once she starts, she runs like a champion. Any ideas? The car has been sitting up for a couple of months in the body repair shop. Any help/ideas would be very much appreciated.

Quoting, because it's easier than retyping a few times a day.

Hard hot starts with good cold starts is a hallmark sign of compression failure. This is because in all rotories, the housings expand faster than the rotors when heated up. In a good compression engine, the apex seals can bridge the gap perfectly fine. However as they wear down, their ability to bridge the gap is reduced further and further, making it harder and harder to start the engine when hot, even though they can start fine when cold.


If there are other details, you might want to include that information.
