Question about 1999 Isuzu Trooper
When in stop and go traffic yesterday, the car suddenly died. It restarted, but would not maintain a normal idle unless kept my foot on the gas. Once we got out of the stop and go traffic it ran ok, but still seems to have at least an intermittent problem with the idle speed dropping to 0 in stop and go situations. Any ideas on the problem? We are traveling in Mexico, so I hoping it's an easy one! Can I continue driving it without fearing that the engine will just quit running?
As well as cleaning the throttle body I would highly recommend if the product is available air flow/mass meter cleaner and clean the air filterer as well

It will probably be OK. But if you can, find a can of brake cleaner and a toothbrush. Remove the air plenum from the throttle body. Use the cleaner to clean the throttle body inside and the back of the throttle plate as best you can. Especially around where the throttle plate sits. It will take a second or two to restart the car. Once started spray some of the brake clean into the throttle, rev it up to keep in running. This will help stop the dieing out.

There are 3 major issues with the V6 Rodeo. The intake manifold gaskets leak. The drive by wire sensor on the gas pedal goes bad and makes it stall or run at just idle (light will come on). And your problem is the wiring harness to the motor. Get under while it is running (best to do on lift) grab the harness and shake it and pull it. Engine will probably die. Sometimes taking plug apart and using electrical contact cleaner on it will work, sometimes a stick of dynamite will cure all the issues with these. My son was almost killed three times in his 2001.

I had the same issue on my 99 Trooper.
It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.
I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.
They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.
Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor
The total cost to me was $345.00, and I definately don't feel gipped.

SOURCE: 1996 Rodeo overheating
Check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.

Replace the speed sensor located on the transmission this sends the signal to the speedometer, you may want to check the plug and its terminals to be sure the terminals in the plug are not corroded if they are clean the terminals with electrical contact cleaner then drive the care see if cleaning the plug fixed it if not replace the speed sensor.
