Bad tires or out of balance tires or driveshafts. Have it checked out.
Yes, either can cause a shake while driving.
it is either the erg valve or the timing is off.
trash in your fuel filter
Maybe the computer,is happening with my 98,Fuel system ok ,batt ok.
Inoperative radiator fan.
Check the oxygen sensor. My 1995 Grand Cherokee stopped stalling while driving after it was replaced.
Out of balance or damaged tire(s). Damaged wheel(s). Engine misfire. These are the three most common culprits.
Check the crank angle sensor usually about $150 to replace
It goes up while driving and down when you're idle....that's normal
I had that same exact problem with a 1995 Jeep Cherokee, and it was indeed a bad oxygen sensor. Relatively cheap repair too.
A universal joint on the driveshaft going bad.
It depends on the setpoint of the thermostat.
