Engine revving at idol and very slow to respond

When driving home this morning, the oil pressure gauge and engine started revving at idol and were very unresponsive to the gas pedal. If I floored it, the engine would slowly increase speed up to 40. Any ideas what the problem is?

Saturn vue just turns over doesnt start

For 90% of cars that try but just can't start. Key off, Pump Gas Pedal 4 x, holding it to floor (all the way down) on 4th time, then just turn key. as soon as engine starts and revvs up, let go of the gas pedal! Seriously... Do not keep the pedal down!!! This is b/c engine is 'cold', the oil that lubricates your precious engine is very thick, and you don't want to add other problems (scarred pistons/cylinders/rings and oil burning or a severely overrevved engine (screaming) at no load (you are not in gear - no drag of car weight on motor) resulting in major engine damage.

My Ford f-150 started this morning but engine shut off with the check gauge indicator light on. Oil pressure is low, oil leaked onto driveway. Engine cranks but will not start. No smoke or burning sme

don't run it with low oil pressure - you will damage the engine. WHere did the oil leak out? Is it staying in now? Not sure what you mean by "check gauge" - maybe check engine? If you can pull the codes from the ECU that may help. WHere is the oil level on the dip stick? reply via comment to the orignial question.

1993 chevy pickup z 71 driving down interstate and check gauge light came on and oil presure dropped to 0. Truck died and cant start again

It could be the oil pressure sending unit, or the engine could really have no oil pressure.
If the oil pressure dropped to zero at highway speed, I would expect the engine to lock up or at least make alot of noise.
You may have to tow it home and check the oil pressure with a mechanical gauge, or replace the sending unit to see if the gauge on the dash reads pressure.
The fuel pump gets power from the pump relay at startup, then runs off power from that oil sending unit when the engine is running.

Low oil pressuer light comes on when at idol

You'll have to determine the actual oil pressure. We use a mechanical gauge fastened to one end of a 3' length of high pressure hose. An appropriate fitting at the other end of the hose is threaded into the opening that the oil pressure sender is removed from. Run the engine until warm and read the gauge with the engine idling. If the oil pressure is below 7 lbs the engine probably has seriuos problems. If the oil pressure is higher than that you probably have a bad oil pressure sender. Otherwise you can just change the sender and see if that corrects your problem.
