If it only happens when the engine is cold and goes back down I wouldn't worry about it. My S10 Pick Up can sometimes read as high as 70 PSI in the wintertime when the engine is cold. Once it warms up it stays between 25 and 40 PSI, depending on engine RPMs. You can hook up a mechanical gauge and see exactly what the PSI is. I think you'll see it's ok. Hope that helps! Jim
No it happens randomly.. Usually right after I get up to a high speed when it happens. I drove 30 miles yesterday nothing happened. I parked shopped for 10-15 minutes came out, started the truck and it was fine. I got on the highway to come home it looked fine but then it jumped to the last line on the high side.
It could be a bad sending unit then. Hope that helps! Jim
