Oil pressure jumps around
This is a really interesting thread........
I have noticed my oil pressure dummy gauge jumping around on me.......first I thought it was the sending unti......replaced that TWICE, once with an AUtozone version and then the Ford version...........
I can be sitting in my driveway and it'll jump from the "M" in NORMAL down to the "N" and back with no movement from the vehicle and no RPM change........
Is this simply a bad gauge or what?? I have a family vacation coming up in a month............about 10 hours each way plus driving on the beach..........LAST year, we blew a tranny.............hoping this year is better..........
Does this sound like a problem?? I noticed this, too, after switching to synthetic and I am just about to do another oil change...........should I switch back to regular oil???? Could this be the oil pump?? I notice this jumping at idel and ehen travelling along...........
ANyone??
