Your Transmission
you need a new rheostat !
Pick a time when the internet is not crowded with other users slowing down the download speeds
Short answer: no. Slower speeds are helpful only for errors during transmission but not quality.
rapidly changing gears in anything will hurt the vechicle but not slowing down will not
This depends on a few things: If your vibration is happening at high speeds, get your wheel balance/roundness checked if this is happening at all speeds, check your alignment/steering if this is happening when slowing down, chances are that you need new brakes
Check your spark plug wires. they seem to burn out at the contact terminals. Ours did exactly as you described. The reason, is movement ( sometime there is contact and sometimes there ain't) therefore variation at different speeds.
Check the fuel filter, it might be clogged.
Bad TPS, plugged exhaust,bad CO2 sensor many things you need to get it tested by a mechanic
Type your answer here... if it is a front wheel drive it could need c.v.Joint's. Just a thought
They are both probably about the same. If you live in a very large neighborhood you may experience some "slowing down" of your download speeds at peak usage times if you have cable.
Had the same thing happen. It was the oil sending unit.
