Question about 2004 Isuzu Rodeo
I have already replaced the throttle body, and the only noticeable difference it made was in my bank balance. So, (I'm told) that the problem MUST be in my mass airflow sensor. Is there a way to test this unit OFF the vehicle with a multi-meter or a jack-hammer or something???

The MaF sensor is inexpensive and easy to chage.
If you are having power problems more than fuel problems, check your exhaust at the tailpipe for the smell of sulpher andwheezing. The exhaust should stop the minute the engine is shut off. Using a tissue you can pick up any exhaust movement after shutdown, Like a real low draft. If so, Consider having the catalyctic converter chk'd for restriction. When they plug up the engine can't breath and loses its power. The MAF sensor cause eratic idling and jerky acceleration.. It's the first sensor in the duct coming out of the air cleaner. Good Luck. - Ned

Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
Forced idle mode--The control module will perform the following actions:
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
Ignore accelerator pedal input.
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.
