I have a 91 wrangler in very glod shape well maimtaimed by previous owner. Got in it this mornjng and it felt shaky. Shifting from 2nd to 3rd it got more shaky. Accelerating in third and shifting to 4th was the same . Like a loose engine mount almost. Once I maimtaim speed its fine. But hitting the gas it starts again. The whole jeep just shakes. Any ideas?

I would check the motor mounts, transmission mounts etc... also check the driveshaft ujoints.

I would check for a bad plug, plug wire, or a plug wire shorting to ground. Sounds electrical to me.

If its new to you, you would be wise to replace all the tune-up replacement items and fluids. That would eliminate a lot of potential trouble spots and you can look at the condition of your plugs to see how healthy the engine is.
