A 2000 Isuzu would have fuel injection not a carb, so no choke is used.
You would need to get the computer checked for trouble codes, I would suspect a huge vac leak is the cause of the fast idle.

SOURCE: some of the warning lights stay on.

so all the lights that come on when you first turn the key on stay on? maybe your alternator is not working properly? or not connecting to your dash panel correctly? or maybe the engine management system has a fault in it? more likely to be a dodgy connection to your dash board.

I would change the trans flter, trans fluid, and have the linkage on the trans adjusted.

After market spark plugs could be the problem.
Reinstall the old plugs and see if that fixes it.
This vehicle has an ion sensing ignition system and is real sensitive to the proper spark plugs. I would get the proper plugs from the dealer if the old ones work.
The codes P1311 and P1312 are ion sensing codes.

Hi.

If problem is only on startup and when idleing, then the problem is likely IAC system, also a vacuum leak will cause the same problem.

If problem is not only on startup and idle, but also when driving, then MAP sensor and EGR system must be checked.

Check also accelerator cable state and setting.

The first thing to do is pulling out the OBDII fault codes stored in the ECM. This is done connecting a code reader to the ECM diagnostic port. The job can be done for a small fee at any local garage, and it is done for free at AutoZone.

The codes will help locating the problem.

About possible faults:

Problem is stalling when idling and during startup, but engine idling fast all the time. Problem not starting at times it is due to the fact that the wrong mixture is being sprayed, this is probably causing flooding and misfire. Since the CEL is on, one of the codes returned is probably misfire.

Check accelerator.

Check IAC system. This is composed by a valve and a solenoid that check and control amount of extra air air when the engine is idling. The IAC valve is located on top of the throttle body.

Check the vacuum system and try cranking with gas tank cap off. Vacuum system is tested using an hand tool gauge onvacuum lines while spraying card cleaner on the hoses (or heating them with a torch). If there is a leak, pressure will go up. A big leak will also do hissing noise, and will often result in a lean code when doing an OBD code scanning.

This kind of symptoms can also be caused by weak wiring to MAP/MAF sensor (MAP in this engine).

If the car also drives very rough and is revving up and down in a weird way, check the EGR valve.

As first thing I would do a code scanning. This car is OBDII. The scan can be done for free at the nearest Autozone, or for a small fee at any garage.

If you get any OBDII code from the scan, report it here, so that we can individuate the possible reason for the problem.

If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.

Regards.

Ginko.

You will have to get the engine computer scanned for trouble codes and go from there. Since the light came on before it stalled out, there should be a trouble code to indicate the problem. And now that the light is staying on when running, it means the problem is still present.
Many auto parts stores will do trouble code scans for free. You can google almost any trouble code and get enough to fill a library, well almost.

My car wont start sometime, my motor does turnover but it wont fire. it seems like its my gas pump


Try cleaning the throttle plate, where the flapper is. Carbon buildup where it closes. Air entering engine after the mass air flow meter will keep from starting easy. Computer doesn't like air it doesn't know about.

Okay sounds like you have a clog within the system, first of all, drain the whole cooling system, run clean water thought the top of the radiator, look to see when the water comes out nice clear, replace the lower hose if you have a petcock close that, refill the top of the radiator, until it is full, start the engine, with engine running turn your heater, let the car warm a little, then reopen the petcock or loosen the lower hose and let the water draw out a little until is pouring out nice and fast, then re-close the petcock and stop the engine.
try and get 40% of the water out, and replace it with 50/50 antifreeze fill to the right point of the cars specs.

In cold temps below 25deg. when engine is first started it acts like the engine is chocking out and won't stay running. when engine warms up it runs fine. 3.3 V-6. is they a sensor that is causing this?


The coolant temperature sensor located near thermostat housing can cause those symptoms. If price at autoparts store seems high, try dealer, sometimes they are cheaper.
