Hey everyone. My name's Alex. I just recently bought a 93 isuzu rodeo and I'm not too familiar with their engines. I have 142000 miles on it and my problem is when driving the vehicle, mostly it drives strong and true. Other times, it will not idle smoothly and bogs a bit, though does not fully stall out or at least have not experienced it stall, and will not accelerate to full potential from a stop. It has a rough feel to the engine and will buck like it's trying to accelerate normally. I have had an autozone guy recommend me change my fuel filter which should be simple, and then tell me look at replacing the fuel pump soon as well. Another guy has told me to look into some wiring issues and/or bad sensor. Not too sure what that means since I'm not really knowledgeable about cars aside from minor maintenance and upkeep. Any thoughts/suggestions/further questions for me would be much appreciated. Thanks a lot. It's a 6cyl, 4wd, 93 rodeo. Manual tranny. Alex.

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.

    Hey swanine, thanks a lot for this suggestion. Have you had experience with a similar problem and solution before? I will definitely look into this in the engine and research it to see if I can locate the sensor. I will get back to you on this on Tuesday since I'm on a double shift all of Monday. Talk soon. -Alex

    hey swanwine, so ive located both the throttle position sensor and the air valve sensor on the engine with help from autozone. The guy there recommended switching out the valve one. He said there was really no way to test and know which one was bad. any thoughts? And which of those were you thinking was the problem? Or could it be a bad MAP sensor. The guy mentioned that as well.

  • swanwine Oct 23, 2013

    I woul'd go with the air valve sensor as that was what caused my grief.

  • alex beat Oct 23, 2013

    Once again, thanks a ton for your help and all. Much appreciated. Yeah I almost bought that sensor today but got timid since I didn't know which to replace and thought about taking it to this recommended shop in town for free diagnostic. Wouldn't be until next week though so i'm kind wanting to just get the sensor anyways in hopes it will solve it.

    I'll keep you in the know thanks.

    Hey swanwine,

    oops, accidentally sent that early, anyways. I went ahead and replaced the idle air sensor, and it seems to be doing better, but sometimes still a flux in idling. Although I would assume that won't help me with my problem on accelerating... Any thoughts on why the truck is still surging or not accelerating strongly. It holds back and then surges a bit like it wants to go normal, but then other times it runs perfectly strong while accelerating. Thanks a lot.

SOURCE: i have a 1994 gmc safari.It seems to have a smooth idle at times

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!

SOURCE: 1998 lincoln continental idles very rough

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!

SOURCE: Idles okay, runs rough when gas applied

Either a bad MAP sensor, or TPS. What is the code for the check engine light? This will most likely tell you what it is.

I just bought an 04 isuzu rodeo with only 75000 miles it seems to run rough and makes a knocking noise and shakes and no the chk engine light is on what do you suggest I do

First thing I would check is timing then plugs and wires. With electronic ignitions, even bad plugs and wires can cause rough running and pinging and knocking, backfire and such.

2004 Rodeo, 103,000 miles. no oil leaks so I guess its burning oil. Oil is maybe a qt. low after 1000 since change. Engine still sounds fine but I don't know what a new engine sounds like since I bought...

if you are using a quart of oil every 1000miles,that is NORMAL FOR A MODERN ENGINE.thats why they last so much longer than the old technology.you could try 20/50 oil when you next change as that will help.but worry when it gets to pint every 350 miles.

1998 Isuzu Rodeo surges while cruising

It is probably the mass air flow sensor, you can try cleaning the small wire inside it (windex works the best) but chances are it will fault again soon after. replacing it is your best option.
