96 Cherokee Laredo

[reyray19]

Just bought a 96 Jeep Cherokee Laredo, when you first turn it on it is fine. It vibrates when you put in in reverse and vibrates again when the RPMs raise until it shifts and then runs smoothly until the RPMs raise again and shift. That's only happens at slow speeds, but completely stops once I get past 35-40 mph.

Don't know what is wrong, can anyone help?

Would you say the vibration is the engine, steering or drivetrain?

I think your throttle body needs cleaning.
