I have a 1999 jeep wrangler 5 speed 4 cyl. When im driving around town there is no issue but when I get on the highway for a while like 20 miles or so and I try to accelerate it feels like its bucking. Any idea what this could be? It got worse today and is doing it all the time now. Thanks

Inspect and test all the following listed below:

Oxygen sensor
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Cap and rotor

Note:If it doesn't apply disregard.
