Oil pump?

My gauge usually reads 22-23 lbs at idol in my rio grandé and around 60-62 in fifth gear at 75 mph but today it all of a sudden became pegged past 80 but still settles down at idol. No matter what gear or what rpm it shoots straight past 80 lbs when I touch the accelerator help!

Either you've spun a bearing and the motors going to blow or your oil pressure sending unit is no good and needs to be replaced.

Well it's still running great would I notice if I spun a bearing? I'm assuming I would.. The other thing is, I had an oil leak out of
My sending unit. It was coming right outing the connector, so I replaced it and it was working fine til my ride home from about 3
Hours away.

as long as its not reading zero itll be fine.80 means you have pressure.it could be a little gunk in it.0 means you need to replace.i have a 94 and its been pinned at 80 for 3 years now with no problems.

Remove it and clean it out, reinstall and try it again, could be a faulty sender even if it's new.
