Check engine light is on so i had it checked and all that is coming up is a throttle position being off so i changed the tps but it still isn't running right and the check engine light is still on. I heard there is a way to relearn the throttle position sensor with the pedal sensor is this true and how do i do that?
Your trooper misfire problem was 1 or more Common rail injectors

Do you know the OBDII codes? I just had to replace my Mass Air Flow sensor, it seems to have fixed my problems. But check the error codes.

The most likely cause of check engine light is the o2 sensor.
SOURCE: 1996 isuzu rodeo keeps reading
A misfire alarm typically means the coil pack mounted above the sparkplug indicated in the misfire had gone defective.
To test it, swap the coil pack with another cylinder, and see if the misfire goes from #2 to the cylinder you put it on.
If the misfire continues to be on #2, then consider changing the sparkplugs.
I hope this helps.

Is there a coil per cylinder? That's sounds like a faulty coil, that can cause a misfire in a cylinder. It's relatively easy to test. Start your engine and when the car rpm's drop, remove the coil socket from cylinder number one and if the car hesitates more that means that cylinder is working good, then reconnect and continue with cylinder number two, remove the coil socket and look very careful for hesitation and reconnect and so long until you check all off the cylinders. If you disconnect a coil of any cylinder and the engine remains the same, doesn't hesitate more, then that cylinder isn't working, so change that coil. Begin with cylinder number 4 if you want to cause of the scanner reference.

http://engine-codes.com/p0101_isuzu.htmlForum CodePossible causes- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor
Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor
