RE: Oil Pressure going UP & Down!

I'm going to assume you had someone or a shop change your oil.
If you did I would immediately take your car to another place as your oil gauge should not be doing this. Worst case is you have an oil leak so check your oil immediately and add oil if necessary before driving.
Most likely someone put in the wrong oil filter and your oil is having trouble circulating since this is a fairly new car!
Also, if your oil was overdue a change.....have it changed again to clean it up as this could just be it's still dirty and clogging the new filter.
I wouldn't worry too much if your oil dipstick is showing it full!
But do a follow-up asap!

I have 2002 gmc envoy, oil pressure low, stop engine warning only comes on when i stop on a hill?


The pressure regulator in the oil pump may not be working, the idle speed may be too low and there may be a lot of wear on internal engine parts lowering oil pressure

I have a 2003 GMC Envoy with 175,000 miles. I change the oil regularly and had a tune up ar 90,000 miles which included a sparkplug change. What maintenance should i do now to keep my vehicle running...


Rear end lube should be changed , Timing belt and other belts should be inspected for wear and changed as well...
Most any decent shop will inspect the vehicle for worn out parts when they service it... ( one of the percs of paying someone else to do the oil change). Have them do the free 27 point service inspection...

I have a 2003 GMC Envoy, trans slipping that I have been towing


Low fluid can cause slipping. (depends upon how low) Most manufacturers post "safe" tow speeds. These are generally ignored. (not good). I recommend towing with driveshafts removed and where driveshaft has a "slip yoke" you install a yoke from a scrapyard and wire it to the tailshaft so it stays in place (keeps oil in and dirt out) Although you can't just detach the tow-bar and drive, it eliminates any possibility of trans damage, since the transmission cannot turn. (most use oil from pump to keep gearsets cool...when towing, pump is not pumping and over time and distance it can damage trans internals.)
Hope your problem is just low fluid and not a rebuild...keep in mind what I said though.

Oil pressure reading in 2003 gmc envoy


No problem with the oil pressure, the norm is between 40 to 60. Anything lower then 40 you have low oil pressure and anything above 60 then you have high oil pressure which is caused by a blockage in the system.
What is common is the oil pressure gage fluctuating for the first 200 miles if the oil pressure sending unit is getting worn. Good maintenance will keep the engine clean and running good but the oil pressure sending unit is inexpensive and easy to replace. Next time you do an oil change you can have them change the sending unit.
Good luck and hope this helps. You can pick up the sending unit at Auto Zone and most auto parts store and will have the step by step to replacing it. If you do attempt to replace it. make sure you DO NOT USE any Teflon tape or silicon on the threads, they are tapered and need a good ground to the engine for proper readings.
