TRY REPLACING YOUR PCV VALVE

it sounds like you have a injector leaking down into one of your cylinders so it is flooding out a cylinder thus runs rough and long cranks.

The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???

check or clean out throttle body at throttle plate it may have carbon build up on it. also make sure air filter is clean and check or replace the intake air tempurature sensor.(iat) sensor. the sensor is under 20.00, the sensor is after air filter in the big hose to throttle body.
