2001 Isuzu Trooper and CEL is on. I changed the EGR valve, cleaned the port, changed intake gaskets, changed PCV valve, change air filter, changed fuel filter and it still is on. It is very sluggish during initial acceleration. If anyone knows what to do next, let me know, The garage told me to change the main wiring harness for $1,500, but the tech asked me for help in diagnosing it. Let me know, thanks.

What code(s) are in the memory? If you have an CEL and, vehicle won't start, number of different possibilities, so if CEL is lit, must be code and ecm problem. Post it for better help.

I need to take it back to the place that did all the work and see what the codes are. They also cleaned the MAS. Since this things burns so much oil, I haven't changed the Oil Filter in awhile. Could that cause issues? I know it is a stupid question, but I couldn't imaging a dirty oil filter causing the CEL to come on.

My ABS light came on. I read the trouble code (43) using the jumper/blink method and was directed to test another relay. Unfortunately, I can't locate the ECBM unit on this vehicle. The 1997 manual shows this under the passenger seat, but it doesn't appear to be under there anywhere. Does anyone know this location?

I just made it to the Autozone to get it checked for codes and I got these..
P1295 - Electronic throttle control power management mode probable codes.
P1515 - Commanded versus actual throttle position correlation.
P1125 - Electronic throttle control limited performance mode-two APS faults set.
My question is... Do these problems fall under power train warrenty ?
Thanks in advance for any help.

I am having this same problem - but it only occurs when it is above 85* outside. Last August it started, I spent several hundred dollars and several having it trouble shooted and I thought fixed.Would run fine, then have the issues randomly. Replaced 02 sensor, idle control, etc. 3 different shops. Then was told maybe needed to have the fuel injectors cleaned, used Lucas fuel cleaner. Ran great all fall, winter, spring (also rebuilt transmission this spring). Last week it started it again. Very random, doesn't matter if AC is on, it will reduce power. If I pull over and let it sit for about 5 minutes it runs great again. The check engine light will also go off after driving a couple of miles. Anyone else have a solution?

Finally I found out this stupid "REDUCE POWER" light on resolution.
It comes in only because your battery is start dying, you would think it's working perfectly fine but in reality it just start dying and not sending enough voltage to your ening.
All other functions will remain working fine untill it really died but for the 4 wheel drive SUVs, voltage has to be on a constant level.
So, if you see that light start coming either try to recharge your battery or replace it with good one.
This exactly what happened to my Isuzu Trooper 2002 SUV. Good thing is that mechanic from Isuzu dealer is my friend and he told me about that. So I bought a new battery and go back to dealer and installed it by myself (coz they are charging $200 just for battery and installation) and now there is no more Reduce Power light.
