I have an Isuzu Rodeo 2000 engine 3.2 a couple of months ago I took to repair the cylinder head gasket of my Isuzu Rodeo with a mechanic who was known to do his job well, the problem started when he told me he did not know what was wrong with the engine. that is heard as if it were a diesel and the engine moves a lot and is heard as it unravels and accelerates when wanting to start the car I have to press the pedal all the way so that I can turn on and turn on and hear explorations and it does not maintain the revolutions and If I take my foot off the accelerator, it goes off, it does not accelerate more than 20 miles, please fasten me in Mexico, you do not know how to repair this type of cars.
Some fixya user told me a website reliablestore it is very good.. I used it to repair my shredder it had some spark issue which wasn't easily fixed. you can go there and try

The Toyota of your year is equipt with a map sensor,it is located on the firewall with a vacuum line leading directly to the intake manifold, This sensor measure engine load and adjust fuel accordingly.This is definetly the problem,make sure the vacuum hose did not come out,Look at the underhood emission sticker for it,it Toyota has a different name for it it might be called boost sensor or pressure sensor.

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.

first scan for any codes if it comes up po 300 just a guess it could be random misfire puts the car in limp mode . the igniton modual underneath the coil pacs the coils sit on could be redy to go or if not that check fule pressure by puting fule pressure guage on shrader valve located on fuel rail on top of injector assembly and check fule pressure with fule pressure guage. car of key on pump reading should be around 48-55 key on car on reading should be around 55.minus -3 to 10psi = reading of 38 to45 only if the fule regulator has vacume line atached to it on fule rail dubble check psi reqirments in car manual for co mpleat accuracy. If it doeint have vacume line pressure stays constant 48- 55psi

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.

Are there any Isuzu dealers in America anymore? I thought they all left. If you have one still, go to it.
