Question about Cars & Trucks
Alex, that sounds like something a bad fuel mix sensor would cause. It is usually located behind the air filter and would be the only thing there with a couple wires attached to it between the filter and the engine. I am not familiar with Izuzu but check to see if you have one as I described and if you do then that is most likely the culprit to your problem. If so replace it. Not a big job.

Im not sure if you got it fixed yet! It could possibly be idle air control valve. But here some more suggestions! I had a 94 Safari van 4.3 liter I was working on for about three days and I finally figured out what was wrong with it. It would run fine for a couple minutes and as soon as I hit the gas and let off it would surge, but anyways I ended up changing the distributer, after the fuel pump and filter, mass air flow sensor, egr valve, idle air control valve, map sensor, and ignition module. So that might sove the problem if you were on the same track with it as I was. Hope this helps ya!

Has your engine gotten wet? Sounds like water around your spark plug boots down in the port around the spark plugs. If there is any water down there, make sure you blow it out with air compressor prior to removing plugs, or it will drain directly into the engine. Another scenario, could be EGR valve or related parts. Is your check engine light on? With that rough of a ride, it should be. If it is an auto parts store should be able to read the code to help pin point the problem. Good Luck!
