Re: engine light on going downhill
What was your oil pressure running? How steep was the hill. I've heard some guys complain when wheeling steep hills their oil pressure drops, alot! Because all the il goes to the back of the pan or when going down hill it all goes to the front of the pan and the oil pump can't do it's job. Some people have baffles in the oil pan for this reason. Next time check your oil pressure guage and see if it changes. Maybe something as easy as a larger oil pan, high volume pump, or oil cooler may help. If not, simply have a check run on it when the check engine light is on. Maybe it's just something simple like an O2 sensor. Good luck, let us know what it turns out to be.
