It it is a very slight shake this may be normal. Engines make vibrations and vehicle design engineers are less likely to waste time and money hiding this vibration on a truck than a car. Generally, trucks are meant to be practical more than luxurious.
If it is a severe vibration, your engine may be running poorly or you may have a vibration transfer problem.
it has a low idle. Can also be a vacuum hose leak.
For non fuel injected models, on the side of the carburetor there is an idle screw. Turning the screw slightly will raise the idle on your Chevy truck.
Check the motor mounts.
vacuum leak?
check the ait. on yhe left side of carb..it control's idle.
Tune up
1500 at first until it kicks down to 850 rpm
Simply replace them. Make sure the pitman arm is bad before replacing it.
No it will not. It only controlls the idle of the engine.
A 95 does not have a idle air tempture sensor, It was not used on that year, no need for one.
While the truck is running in idle pull out the dip stick and read it.
either the idle is set too high or your timing is advanced too far.
