You more than likely have a idler sensor bad. It could also be a O2 sensor. Is your check engine light on ? If so, you can take it to Auto Zone and they will check it for you for free.

I have a 98 isuzu rodeo and it wont stay running unless I keep my foot on the gas. The check engine light isnt on so I have no clue what to do, can anyone give me some suggestions please?


hot or cold engine,or both????????????????????
sure...
the ECU works OVERTIME; hard, to keep the engine running.
this is done by the action of the ISC valve.
so can you keep it running with a fast right foot??????????
a real mech needs to drive car.
does it have full power on hills?
is the tune up service done, the 60kmile repeats and needs to be done.
the ECU can not keep idle right on any engine that runs like crappppppp.

1: all fuses good.
2: engine never warms to normal 180F+ temp and hold???
3: not tuned up.
4: engine misfiring.
5: engine flooding.
6: engine starving for fuel.
7: OMG, the ISC wires fell off, (inspections do work on old cars)

there are simple tests. for each case.
one more #8. EFI system lost 12vdc power. stalls.
12.6vdc not running, 13.3v -15v running.

98 Isuzu rodeo turned car off while in drive gear now won't restart


shutting off while in drive should not hurt anything-do you have dash lights when you turn the key on-will the engine turn over when you turn the key to start position-is it firing at all-let me know and I will try to help you-Denny

Re4place the thermostat.It actually sounds like the thermostat might have been put in facing the wrong way? The copper pellet side has to face the engine. That's my first guess,anyway. post back and keep us informed. don-ohio (:^)

Holden Rodeo 2001, check engine light keeps coming on!?


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???
