Cleaning the injectors may fix the problem. I've had similar problem of poor acceleration, loss of speed uphill though it's fine at low speeds. I had the injectors removed and saw the build up of hard deposits which can only be cleaned when the injectors are removed. My car works fine now.

    Another cause of power loss in diesel engines is clogged fuel filter. Some vehicles have additional fuel filter INSIDE the fuel tank. I had my tank taken down and the inside filter cleaned and it fixed the problem. Some petrol stations and repair shops provide this service.

    If replacing the fuel filter in the engine compartment doesn't fix the problem, try this one.

Why does my engine go dead when I turn my ac on in my 2001 Isuzu rodeo?

stalls, is the word.
here they all, each takes, simple tests.
  1. battery weak.,and dischaged for 3 possible reasons, 12.6v id good 13.3-15v good running. not less.
  2. A/C compressor seized.
  3. ISC/IAC bad on the engine, idle controls totally dead. RPM low.
  4. Horrid loss of engine power, if car will not move fast , this be it.

i think that is it.

I'm having same problem on my 2000 model rodeo 4wd 3.2L V6. Other day check engine light came on. I checked engine bay nothing abnormal, or power loss. Next day light was gone. 2 days later drivin

Where I live there is a Schuck's auto parts...and they have a hand held diagnostic tester that plugs right in to your harness. This will tell you whats is wrong.It only takes about 2 min and they don't charge you.On my car it was the mass air flow censor.If you can't find a Auto parts store that does this...take it to a shop soon. Good Luck

My 2000 rodeo manual trans. had a loss of power

This sounds like a restricted exhaust system, may have a clogged cat-converter,i would start by checking the exhaust system,and also check the engine for loose vacuum hoses

98 rodeo 4cyl. why when i turn the ac on i loose engine power?

The cause of power loss is that the engine idle is not being increased when the A/C compressor comes on.

This is either accomplished electro-mechanically with an idle-up solenoid, or electronically, with an engine control "computer".

An idle-up solenoid fault is fairly simple to diagnose.

If you have the computer controlled idle up system, I would suggest using a garage to get a diagnosis.

More info? Let me know...

I'm having same problem on my 2000 model rodeo 4wd 3.2L V6. Other day check engine light came on. I checked engine bay nothing abnormal, or power loss. Next day light was gone. 2 days later driving, a sudden loss of power and light came up. After idling for a couple of minutes, drove off with light still on but all power back. 1 hour later of faultless driving loss of power for a minute or so. Engine temp normal. Had break for 1/2 hour and set off for last hour of journey without fault except check engine light still on. Following dayon startup light went out???

92 Isuzu Rodeo Power loss

Do you have the v 6 or the 4 cyl.?
You may want to check the cap and rotor, and check to make sure all elctrical connections and vacuum hoses are tight and in good condition. Then go from there.
