    my 1997 chev 1500 2 wd 350 with about 15000 oil presure gage reading 60 psi the goes down on right side of gage NOT ZERO side. These GM from 96 to 04 have very bad electrical problems and water lost problems. I have just finished replacing intake gasket with FelPro gaskets and still lossing water. No signs at all outside of engine and runs great. The oil gage acts like loss of power to the gage, it now stops working when brake is applied then works good when brake is released. Anyone who has found this problem fix can email me

You had better check your dipstick and see if you have any oil showing on the stick? Sounds like your oil pump pickup is uncovering in a turn and cavitating which is caused by low oil quantity.

I have a 2003 ford ranger the oil pressure guage goes to hald way then 0 back to half way truck runs great with no problems

Check the plug first. Look at the tabs in the plugs. They should be touching from one side to the other. See a gap fix or replace the plug. If it looks good, Replace the oil sending unit.

My 1995 Mazda B2300 Truck, 2-dr. 4cyl. When driving up hills mostly, it engine sounds like it's dieseling, loses power, and the oil gauge goes crazy. Help?

Check your vacuum pump, that pump does all the switching of your sensor valves and ports. That would be my guess

The oil light come on when I turn right in my 96 ford taurus

It depends on what the problem is.
It could be a problem in the wiring, or you could really have low oil pressure.
If the engine oil level is up to the full mark, I would check the pressure switch and the wiring. You may need to connect a mechanical gauge and drive it to make sure the pressure is normal.

My 1995 Chevy tahoe is hard to start, runs rough when you start out, has high oil PRESSURE

not enough info, what engine, fuel injected? if so what type, multi port, or throttle body? oil pressure is not the problem, it could have a Hi-Perf. oil pump. fix the leaks, they will make a horrible odor. and coolant leaks will make it run hot.

Oil pressure low when idling. When running engine

first check the oil level if its good then change the oil if you hav'nt done so all ready and add some LUCAS oil stablizer this may help alot if not then the oil pump is most likley going bad and needs to be replced before the engine lacks oil and cause the engine to seize.

My oil light is on . I change the oil i change the oil pressure switch . I check the pressure with a gauge it goes to 50 when i start it the engine is very quiet but that light drive me crazy please help...

the oil pressure sending unit must be defective - it should be located close to oil filter - if another sending unit is purchased you can compare the two - most sensors only plug up one way - the light should be working thru ground - light may not come on if sending unit is unplugged as a test

Oils pressure gauge fluctuates

check the oil viscosity,it might be too old(driven for toomany miles)..

if thats not ityou might need to get the oil preasure lubricating pump checked,and id suggest you do it fast or theres a lot of engine wear and tear.
