In an earlier post, I mentioned that the oil pressure needle would peg just at, but not on, the 3 bar line. It now pegs above the line, and the idle, in gear, with a hot engine, ranges from.7 to 1.1.
In the last couple of days, I noticed an occasional click or pop from the speaker area. This occurs when the radio is on and off. At first I thought it was radio static, or a speaker wire issue, but realized that was not likely if the radio was turned off.
Today, after the click/pop, I noticed the oil pressure needle was pegged well above the 3-bar line, so I am beginning to suspect that a loose or improper connection in or behind the cluster is causing my oil pressure needle freakiness. (I could be mistaken, but I am sure I also saw the fuel needle momentarily jump back and forth a few days ago.)
Is there a relay, switch or electrical connection in the relay box, or in the instrument cluster, that would affect the oil pressure (and other) instrument gauges?
