Why do the rpms suddenly drop to 0 when driving on the highway?

It appears that you may be suffering from the same problem i had a while back. Have you checked the wires to the alternator or even the plugs because the rev counter on a lot of cars runs of the alternator. Or it could be the alternator on the way out.

Timing for a 1972 olds 350?
350 cu in with 2 barrel carb, 8 degrees at 1100 rpms 350 cu in with 4 barrel carb and standard transmission, 8 degress at 1100 rpms 350 cu in with 4 barrel carb and automatic transmission, 12 degrees at 1100 rpms
Will spark plug gap causes a RPM gauge to go up and down while idling?
The spark plug gap can cause the RPMs to fluctuate, while idling. The more probable cause of the fluctuating RPMs is a bad camshaft.
What does it mean when your car starts but dies when the rpms get lower than 1 or when you make complete stops?
The idle speed solonoid needs cleaning or replacing or carb needs overhauled. The EGR valve could also be stuck in an open position. The EGR valve should be closed when idling, otherwise the engine will die. When driving at town/city speeds or higher, the EGR will be open.
What causes a 1998 Malibu 's engine to rev at 2500 rpms when first started by the way it won't kick down unless you shut it off a start again then the rpms go back to 1000- car seems to start slowly?
Check the engine for proper cylinder compression. If the pressure is low then a blown head gasket could be leaking and causing the problem.
Why do car cylinders loose pressure?
because you run them to hard and it causes wear and tear. Specialy when you drive alot at high rpms it causes metal to metal.
What is the normal RPM range driving at highway speeds for a 1994 Jeep Grand Cherokee SE?
2-3 rpms
Is it bad to accelerate in a 1996 Camry with 228K on the clock at 3000-4000RPM will this shorten its life or not if so what are good RPMs to accelerate without hurting it?
No no no, 3000-4000 rpms is the average speed for highway traveling, driving too close to the red mark on your rpm is bad
Can you drive a truck with no overdrive on a highway the overdrive has to be looked at it is about an hour of driving on the highway?
Certainly. It's been done for years before overdrive became a thing... it just means you'll turn higher RPMs at speed, and you'll want to drive slower if you're conscious about fuel consumption. I had no problems when I took my 87 Silverado with a Muncie 465 direct drive transmission on the highway.
What would cause a rise and fall of RPM while idling in gear?
the rpms should rise and then drop no more then 500 rpms when the fan on the radiator turns on and then off.
Your 1992 voyager does not seem to drop into proper rpms so im 5000 rpm and 65 mph?
If your 1992 Voyager does not seem to drop into the proper RPMs so that you are running at 5000 RPMs at 65 miles per hour, the timing belt might need adjusted. It can also indicate the idle is set too high.
What causes a vehicle's RPMs to rev up while driving?
If you accelerate and the transmission shifts to a lower gear of the overdrive disengages the RPMs will increase. If the vehicle has a manual transmission a slipping clutch will cause the RPMs to increase if the clutch is defective.
What difference does the ratio make in a limited slip differential?
in relationship to engine rpms a ratio of something like 3.08 would have less acceleration and lower highway rpms compared to 4.11s. the 4.11 ratio would give you better acceleration and less top speed and lower gas mileage at highway speed
Is running an 02 Pontiac Grand AM at 2000 RPMs regularly when driving too high RPM?
NO
What can you do to get better gas mileage on your 2000 grand prix?
First make sure all your tires have the same amount of pressure about 35psi/40psi(22's). Also city driving is the worst try to get more highway & keep your RPMs under 3(3000)!
How is Tractor trailer down shifted?
If you don't know how to downshift (and upshift) and unsynchronised manual progressive shift transmission, you really need to go to a truck driving school. You're not going to learn how simply by read about it. In school, they'll teach you to drop the RPMs down to 1000, pop it into neutral, kick the accelerator to 1500 RPMs, then drop it into the next gear. It might look simple enough on paper, but you're not going to get this down without some hands-on experience.
What happens if you go too fast in first gear?
If the rpms are to high for to long the engin will over heat and you will drop it
What if your 1994 Cadillac eldorado with a 4.6 northstar dies everytime the rpms drop?
Try replacing the map sensor
