Question about 1990 Ford Bronco
Oil pressure might actually be a bit high for idle. High or low oil pressure in an older engine tends to be indicative of some serious issues. Oil pressure that is too high tends to be a clue that you have serious carbon build up. That aside, have you tried running a higher octane fuel, or perhaps adding an octane booster to your normal grade? Pinging can become knocking in a badly worn engine. One recommendation: At your next oil change try substituting a quart of marvel mystery oil or lucas engine oil treatment in place of one quart of your normal oil. Both have some pretty good track records for helping to free up sticking valves and break up carbon in older engines. I'm an old timer myself, and I personally swear by Marvel for older engines. There is no "rebuild in a can" but Marvel comes close. Give those a shot, let me know what happens.
