SOURCE: reduce power and check engine lights on

reduced power usally points toward a gas pedal to throttle correlation meaning the drive by wire system is where the problem is

My Isuzu axiom 2001 model always show reduced power and the throttle will race up please,tell me the problems I have. I changed plugs? and throttle mouth(huh), still the same problems is there.


ever get a full tune up this decade? yes/no.
no , then what are you waiting for, some guy to charge you for new engine with only bad spark plugs>? or fuel filter? or air filter?
which engine, be the first in 100s to say.
most dont and expect helpers to be like god, clairvoyant.
or super man with 12,000 mile xray eyes, really?

2004 has 6ve1 V6 but not in a 2001.!
2004 last isuzu car here. became rebadged cars. GM
but the 2001 i think is a Rodeo, so says the wiki!

If the gas foot causes engine RPM to raise super high over 3000 rpm and not attendant car speed increase(mph)this is called transmission slip. is it slipping , no? then its a weak engine
easy no ?
we dont have these parts in USA>????? change pluck and tortle mouth if fact , perplexing to read....

weak engines> facts. all.
reduced power has any causes, over 50, so will not cause you to go broke with my silly wild guessing as seen here. every day.

the engine power can drop from 3 reasons.
besides a bad engine, 25 reasons there.
in physics they are, (a good engine with full compression tests ok)
  1. lack of fuel (low fuel pressure)
  2. too much fuel, flooding misfire.
  3. and huge list of causes of misfires
  4. lost power misfiring is violent and engine shakes. (bad spark?)
  5. lost power feels only like dragging weight we call bogging.
  6. and is usually fuel pressure loss. or weak injections.
  7. bad sensor to the PCM , scan the PCM and win.
  8. lots more, but no thesis today, just a short list.
so you have 2 choices
get it fixed
or buy the tools and DIY ,
fish or cut bait... we say.

my guess get it fixed, the tools can cost.
$20 each
and if need to buy them all $100 (buy them as needed an win)
and a $100 scan tool.
or barrow one, buy one or ask any shop in town, hey mista,
can yous, scan me car for free?

now my wild useless guess
get a tuneup.

Reduced power light is on in my 2001 Izusu Rodeo Sport


the Reduce light, is not transmission , light correct?

what country are you in., ( asked 10000 times zero answers .well 3)
what engine,? we cant guess engines, here, and it seems to be just that, the engine issues.??? felt is real;. sure..

is the tranny stick or auto...... autos can slip and go to limp home mode just like engines do. so what transmission?

if in USA all scan tool made will scan an ISUZU. 1996+
so then you see DTC errors. and why its in limphome mode.
"your reduced power deal"
there is no other way,,,, besides, 1000 pages i type on how to test EFI with not scan tools.....I can do it. but refuse. to type that here..
as one famous poster said.
you want 50 years experience on 1 fixya page. :LOL

i wont say that, I say.
1: check all fuses.
2: make sure battery, voltage is 13.3 to 15v running, if not you have charge system failures, fix that first because EFI will not run on dead batteries, ever. (discharged for any reasons)
3:Scan it. do so and tell the DTC errors, im sure you have them.
4: or did you skip the 60,000 mile major tuneup, or never did one this decade,,,, wow, that be why , huh?

Isuzu engine 4jh1 3.0 l diesel timing marks


Rodeo with a diesel , non turbo?
this is usa forum with usa book, is your a USA car?
seems not.
now year stated, is this a test. 1991 to 2004 , wow.
im not going to look up all years for you and see if they vary.
why would we....?
cam timing, or pump timing.
we must guess that too?>??????????????????

point finger to something and say, this thing,,,,

here is the wiki blurb on 4jh1
The 4JH1-T is a 3.0 L OHV direct injection engine, turbo intercooled which replaced the 4JB1T in the Faster/Rodeo pickups. This vehicle was sold as the Holden Rodeo in New Zealand and Australia. On some models it features an electronically controlled injection pump. Stock power was 120 hp (88 kW) and 245 N·m.

why ask USA gringos about non USA cars.
and for sure not telling your country, that be bad.

see the word, electronically there.
we cant guess that , either.
