Ok, second question for you guess.  When I am driving and come to a stop at times the oil pressure light will come on.  How do I figure out what is going on here?  I believe that when I changed the oil I used 10-40 but might have used 10-50 and it is a 292 with screw on oil filter.  I checked the oil level and that is still fine.  Any help would be great and please be specific about directions because I am a shade tree at best with these engines.

thanks again
