1995 Rodeo hesitation

I have a 1995 Rodeo with about 160K miles on it. When I am on the highway and step on the gas, I feel jerking/hesitation. The jerking/hesitation goes on for a few seconds and stops. It seems like it only happens when I step on the gas or give the car more gas. When I am cruising along at 60 mph it is fine until I step on the gas to pass someone, then the hesitation kicks in.

Do I need new fuel filters? What could be causing this?

How long has it been since the Plugs and wires were changed?

It could be a Fuel Filter if you haven't changed in a while.

Although it runs fine at a steady sixty mph when you step on it the wires or plugs may be breaking down due to the increased load.

Hope that helps

could be that, or dirty injectors or a weak electrically system

I just had a tune up and had all the spark plugs changed about 2 weeks ago. I have never changed out the spark plug wires yet in the car.

Could this be a transmission problem? I seems to be happening at speeds above 40 mph. Lower than that it is fine.

How much does it costs to clean out the fuel injectors?

I was under the impression that if the fuel injectors were dirty, the ECM would pick up a lean condition and store a fault code. Am I wrong?

I had the spark plug wires replaced and the problem went away.

Thanks everyone.
