When I first got the car 1.5 years ago it was extremely hard to start, once I replaced the sensors right away it was much much better. The sensors currently test out good. It only occurs when the engine is hot and is restarted after 20+ minutes....then it doesn't want to start (but it always does within 2 tries)
