Anybody had any problems with wiring like on my truck when i turn on the truck and it says wait to start i wait of corse but after it goes off and i start it the wait to start light starts flashing. The low oil gauge will go haywire when i'm just setting still idiling and the lights dim and brightin really fast too. Old age or what?

 

The flashing WTS light is caused by an open circuit in the manifold temp sensor circuit. The blinking lights and oil light are probably a grounding problem. Find those grounds and tighten them.
