If the engine doesn't recover, the timing belt (if applicable) could have let go otherwise it could be a fuel delivery issue (dirty fuel filter, faulty fuel pump) or a restricted exhaust (damaged catalytic converter). If you have a check engine light illuminated, start with checking the codes.

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

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.

Much quicker off the line, but the trade off is lower top speed and higher RPMs at highway speeds.

major vacuum leak?

Is chev 400 v8 an interference motor?

No it is not. Before it would hurt the valve train, something would have to happen at a very high RPMs. The timing chain going out will not hurt the valves are the head.

A front or rear hub bearing assembly going bad could sound like that.

92 Toyota Corolla the Idle speed suddenly jumped from 1000 to 2500 rpms when put into park you adjusted the idle screw as much as possible. got it to 1800 rpms. What else can be done?

Check the timing and check that the cable to the accelerator is adjusted correctly.

What could be causing a 2005 grand prix with 14000 kms to have ticking sound that does not increase with RPMs it seems worse when engine is warm and poor performance especially at low speeds and RPMs?

VALVE LIFTERS... the fact that the ticking does not increase with rpms rules out valve tapping or worn piston pin but is indicative of the bearings going bad in the water pump which also would explain the loss of performance.

Why does your 1999 pathfinder jerk when you go over 2 RPMs?

2 rpms? Your automobile engine probably runs around 2000 rpms. At 2 rpms the engine would stall and stop. However, many automatic transmissions jerk a little bit as they shift gears. I suspect this is what is happening to your Pathfinder.

How many RPMs does ford explorer 02 runat at 70 mph?

It would depend on the gear ratio and transmission. stock tires 235/70r16: auto(O/D) with 3.55 gears =2160 rpms auto(O/D) with 3.73gears = 2270 rpms manual with 3.73s = 2360 rpms

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

What speed do you shift a 9 speed transmission?

Situation dependent. Most schools will teach you to upshift at 1500 RPMs with any transmission. Which is fine and dandy if you're running long distances on flat terrain, and won't be shifting much throughout the day. But if you're going up mountains, or going from traffic light to traffic light, you're going to bog your motor down severely, and reduce component life. In these instances, you want to shift between 1800 - 2000 RPMs. This means you'll also catch your next gear in a higher RPM range than you would if you shifted at 1500 RPMs.

Why would your RPMs spike for 10secs on and off but the car seem not to shift down or up and the car not accelerate on a 2000 Grand Prix GT?

because the engine needs to have a 20 seconds RPMs
