I was having a problem with starting when hot. The engine would turn over but not start for a few seconds. If I would turn the car off, then try a restart, it would sart immediatly and run fine. The exhaust was "rich" smelling.

I used an actron scanner in "SLOW code" with engine running. This found the problem with the ACT saying the circuit was open. I replaced the ACT sensor and everything was fine.

This didn't show up on the key on, engine off tests.

That sensor was only a year old too.
