I'd be curious to the miles on the engine, possible worn rings, poor compression. Start with basics first, be certain there are no vacuum leaks, next look to your fuel system; possible failing fuel pump (low fuel pressure) dirty fuel filter? (I'd start with the filter first, cheapest fix if it is the issue) other concerns could be injectors, plugged or failing (poor fuel spray) run a fuel systems cleaner for several tanks see if it will improve; but change that fuel filter first. Also the volts dropping off would make sence if the engine RPMs drop way off, too slow of a speed the alternator will make little if anything.
I hope this may have helped,
Tom

Its a 1995 chevy k1500 5.7 when in park my oil presure reads fine but when i put it in gear my oil presure drops down to almost stalling


This is odd but somewhat normal. This is the way the electronic gauges register. You can try to replace the oil sender to see if it registers different but as long as it shows some increase in pressure when you rev up you should ok. When you put in gear the RPMS on the tach will drop , thus reducing oil pressure. Also,not knowing when you changed the oil last you may just have worn out motor oil.

My 2005 dodge magnum is stalling somtimes completly shuttig off rpms stop movin and engine light is on


More information is needed: When does the car stall? Is it hot or cold when it stalls? Is it after servicing/refueling when it stalls? Have you done any modifications?

Any extra information you give can help us find a solution to your problem.

My 1996 GMC jimmy wants to stall when I come to a stop. The RPM gage goes up & down then drops below 1000 RPMS and stalls.


I would go down to your local auto parts store and do an alternator and battery test. It sounds like at low rpms you are loosing volts. When you apply the brakes you would be supprised how much power from the engine it takes. You could also be loosing oil pressure. Check your oil level. When your engine drops low rpm, the oil pressure drops and shuts down the engine.
