it might be a broken motor mount. there are two mounts located towards the bottom of the left and right side of the engine make sure you are getting spark to all cylinders. (check for Misfiring)
The engine management system may not be adjusting for the extra load of the A/C. Can also be the A/C compressor is seizing up. Have this looked at by a professional.
Break Me Shake Me was created in 1996.
Fair Shake was created in 1989.
Christi Shake is 5' 7".
Shake It Up Tonight was created in 1981.
Check the motor mounts.
My guess would be wheel balance.
There are several things that can cause your 1995 Chevrolet Blazer to shake when accelerating. Bad spark plugs and spark plug wires can cause the vehicle to shake. Tuning up the engine may eliminate the problem.
Cylinder misfire. Possibly failed or failing engine mounts.
It's almost always warped rotors.
Sounds like you blew a cylinder in the engine.
YES it can, but the engine would vibrate and shake if it did.
.039 to .045-----i preffered .041 it seemed to make the engine shake less. but its hard to get them to run nice and smooth. your engine might be different , i did several gap ranges . .041 worked for me, ran fairly smooth.
Im not familiar with this car but it is likely to do with the engine wobbling due to lower than usual idle speed of the engine or a misfiring cylinder. Also if this vehicle has auto transmission and air-con are factors to be considered. For example, if this has auto transmission and it is kept in "D" whilst stationary, there will be load on the engine, which at idle speed can mean that the engine slows to a point where it "wobbles" with every piston stroke almost. The same will apply if air con is used when idling. If there is a misfire on any of the cylinders this can often be accompanied by a loss of power.
Possible broken motor mount(s) Can also be cylinder miss, or vacuum leak.
If the check engine light is blinking , that means a cylinder misfire has been detected
Due to the fact balancing the engine would be impossible. It would shake itself to pieces if it ever ran. It would be very heavy, shake the car apart and have no torque
