You may want to check fuel filter. Bad fuel can cause it to clog making it run and lug around.

74 VETTE WITH 350 zz4 ENGINE 62mph THE rpm's at 3,000 and screaming (red lie starts at 5,000) what is my gear ratio and what should it be for highway driving


Assuming the tires are close to standard (i.e., 275/60/R15), this means you probably have a 4.11 ratio rear end in your Corvette. This was a very popular ratio on Chevys for drag racing. For highway driving you would want a higher speed ratio, such as a 3.55 or 3.36 ratio (or even a 3.08), depending on what is available. which would give you 70 MPH, 75 MPH, or 80 MPH at 3000 rpm.
You'll need to change the speedometer driven gear in your transmission for your speedometer to be accurate if you change the gear ratio.

2008 dodge caliber sxt When traveling on highway between 60-75 mph, and apply the brakes the car shakes. What could be the cause?


Go to a machine shop and explain the problem. More than likely you have a rotor that needs to be turned. Because of warpage

High rpm at highway speed


No idea why you would drive that fast,
but 2800 is about right at that speed

Did you just get the car & never own one that
went to 2800 at that speed

Tap the brake around 55 & see if the rpm goes up,
indicating that torque converter lock-up is working

Don't do that at 70 mph

Front End Vibration


When you put the vehicle in drive with your foot on the brake, and you hear a clunk. You may have a bad CV joint or axle. If not it may be a bad wheel bearing. Those would be the first two I'd Check. Outside of that sometimes poor wheel balancing or a tire belt separation. Either way it should be looked at before you hit 75+ mph. I had a Honda that I had just got off the highway with my wife and 3 month old daughter in the car. On a side street pulling away from a stop sign. The right CV shaft let go and dropped the wheel on the ground. There wasn't as much as a shimmy or a groan prior to that. If we had stayed on the highway another five minutes, I can only imagine. Please check it out for your own safety.

1999 Jeep-violent shaking of steering wheel when braking at 55 mph and then stops when speed lowers to say 40 mph. Only on highway, not streets. When first happened, installed new rotors and brakes, but...


1. out of balance tire because it sounds speed spacific.
2. worst of all! Loose lug nuts or possibly loose spindle nut. (you will need to lift the wheel off the ground to tell)
3. worn linkages i.e. ball joints, steering linkage, anything that would allow play in the front wheels.

Stick shift # Automatic RPM


That is normal,If you do the same speed in 4th gear the rpm's will almost double.

The rpm's will repond faster in a manual than an automatic.

In a manual the engine supplies the power required directly to the gear that you have selected thus the engine rpm's will increase or decrease as needed.

High speed vibration


try checking your bearings on both sides. as for your brakes when you change your rotors try changing both of them as well as your pads. i had the same problems and that fixed it. if it persists i would look at your ball joints and then your calipers. good luck.
