My mustang sits most of the year in a garage, living in pa I only drive it during the summer months. I guess from sitting I have a issue with the oil pressure gauge it comes and goes. When I start it up gauge sometimes does not move then within 30seconds or 2 min it starts working. Sometimes when driving down the road it jumps up and down instantly. I have checked the engine and its not that. Question is anybody else have this issue? Gauge or sensor ? I have not really looked into it yet maybe this weekend . Thanks for any info.
