I pick up an intake, (like below) put it on my truck and it worked great. I took it on a trip to ikea about 70 miles. The drive up there went fine. On the way home with about 500lbs in the back of my truck about 10 miles in the check engine light and the slip indicator lights both came on.......It was raining out side and still is but neither light has gone off. I have tryed the 3 different adapters it came with..... Any help would be greatly appreciated!!!!
