My 2000 Ram has a knock at around 70 miles an hour, and the engine light would flash, then go out. The knocking happens a lot, this morning was a first for the light. On my return trip, I never went above 70, it didn't knock, and the light never came on. Any suggestions?

Also, anyone else have a problem with the passengers side dashboard cracking? I've got a good size crack in the top of mine.

 

If the light came on get the codes read and find out whats wrong...as for the dash...they are horribe, mine s cracked in 5 places and its common for large pieces to break off and leave giant holes in your dash...there re covers out there that look pretty good, but they aint cheep.
