Rough Idle Shakey Engine And Hesitation
 

Hey how you doing? I need help
I have a 1987 260E with about 128,000 miles.
I just got this problem with the car. In Idiling the care is very shakey, then engine shakes so much that it vibrates my exhaust and hits the body. I checked and cleaned the intake and also checked the wires and spark plug. Everything seems to be fine because i just got a tune up recently. When i drive the car the engine is very hesitate. Its like your pumpin the gas pedal. Its like the gas is going on and off on and off.If someone could please help me to do some testing? or help me out. If not i think i will just go and take the car to get a diagnostic check up.

Thanks all.
