... Is going crazy. As soon as the tach gets to 2k the pressure goes past 80 and wiggles real bad. Pulled the plug and the gauge shot past 80 and stayed. At idle and below 2k it's normal pressure. My brother said there was two on his xj, it was a 97. I have a 96. I can only find one. Anyone able to help me with this? Ideas? Anything? Thanks guys.
