Question about 1999 Isuzu Amigo

1 Answer

The brake indicator and battery indicator light comes on when the car is running or idleing at less than 1 rpm. . once you step on the gas and increase the rpm, the indicator lights are no longer displayed. there is no issue with the brakes and the brake fluid levels are correct. There is no apparent issue with the battery as the lights do not dim or brighten while driving. What would/ could be causing this to occur?

SOURCE: 98 Isuzu Trooper stalls on cold start, idle issues..

I had the same issue on my 99 Trooper.

It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.

I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.

They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.

Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor

The total cost to me was $345.00, and I definately don't feel gipped.

SOURCE: Brake fluid leak on driver side rear wheel, anti-lock brakes area

you should be looking for the drivers side wheel (brake) cylinder it is inside the drum with the brakes at the top usually, look at the cylinder on each end there is a small black rubber cap, pull it back a little in one spot and see if brake fluid runs out, if so replace it. Also possible that the brake line is leaking, so check it out too.

SOURCE: Alternator keeps going bad - three so far. Battery light flickering off/on now.

Having worked for an Isuzu dealer I have seen this a lot with aftermarket alternators from places like auto-zone, napa etc. For some reason they will do strange things in these vehicles. The fix was to get a Isuzu alternator. We did have good luck with Beck Arnly alternators also. We also had a local rebuilder repair some with good luck too. If all else fails get a used one.

SOURCE: Shake/Shudder while depressing the brake.

I just changed the brake pads and rotors on my father's 2001 Trooper that he recently purchased because they were shaking just like your were.  He bought it from a mechanic shop and they had put new pads on it but it needed new rotors as well.  If there is noticable groving on the rotors and new pads are installed it can create shaking, sometimes severe, when the brakes are applied.  It sounds like this is what has happened with your vehicle as well.  That being said, I don't consider it a huge safety issue to drive it until you get it fixed, just know that your braking will not be optimal and that it will take you longer to stop than if the brakes were working properly.  All that being said, get them fixed ASAP so you don't have to worry about it.  Who wants to mess with safety right?  Good luck, hope this helps!

When i come to a stop the car wants to die unless u keep ur foot on the gas

Hi Wendi:
If the engine runs fine except when you don't have your foot on the gas, maybe the idle stop needs to be adjusted. With the engine off, have someone step on the gas pedal while you look at the linkage at the carb. There should be a plate with a screw in it that keeps the butterfly valve from closing completely. This can be adjusted with the engine running. (SAFETY FIRST - MOVING PARTS CAN BITE)
If the engine will only run at not nice too high RPM, chances are that the idle jet in the carb is plugged, and a carb cleaning and possibly overhaul may be needed.

Dash lights brake and battery are on always

running? at 800 rpm not 300?
brake failure, read oper. guide what does is say.
it says, first brake fluid level.

my guess is engine was stalled, or was idling at 300 rpm and you fail to noice that?
after all the charge lamp only comes on stall (or near) or bad ALT.

1990 isuzu pickup 4cl often will NOT idle at very low rpms/under 15 mph unless I ride the brakes/E-brake and gas at same time. I know for sure I have a cracked ( in two places) exhaust manifold. The...

this car EFI, or CARB, ill toss COIN, EFI gas.
what 4 cylinder, name it there are 7 used.
I'll now toss my coin land on GAS 4 cylinder engine. (in usa?)
is it racing too fast hot
or RPM too low hot.?

we cant guess what your statement above means.
the exhaust manifold cracks will cause the 02 oxy sensors to LIE,
to go lean (0volts ) this cause the fuel injection
to go RICH, (cause and effect closed loop rules)
and can idle too slow. (see that word SLOW)
the wrong word you used, after reading this vast times.

"NOT idle at very low rpms"
i decode this to mean?
NOt idle at proper low RPM (800 hot)
or spec 800 rpm , is more clear
that means the idle races hot.
this word is in all books on cars. engine RACES

IF true RACES it's not :
the exhaust crack, but can be if engine EFI slams in to limphome mode, do the flash codes show 12?
you never did those did you , bad idea skipping that. Google isuzu diagnostic jumper and read.
it's not he fuel tank ever,. not RACING.

what can cause any map based engine to race
well frankly LOTS:

but can be reduced to: (physics +)
1: throttle cables jammed. no slack. bad.
2: throttle valve jammed (gunk below it does that)(in the throttle body)
3: all vacuum leaks, (put huge list here, ask)
4: ISC or ICA valves stuck open
5: engine not reaching and holding 180f will cause #4 above to fail, naturally. bad thermostat. cause.
6: someone hacked your TB. (ask)
TB = throttle body.

vacuum leaks is an all day wall of text post
i refuse. but do have links to them.

Hi yaris is running rich, has poor gas mileage (360km on a full tank). and very slow and choppy idle (idles like a really old car) these are the things i have done so far : change air and fu

Do the following:
1. Clean the throttle body from inside.
2. Adjust the spark plugs gap to 1.00 mm.
3. Check fuel pump pressure. (44 Psi - 49 psi)
4. Remove the negative battery terminal for 5 minutes.
5. Connect the battery terminal.
6. Check the engine oil level and coolant level.
NOTE: Before starting the engine shut off all lights and loads for example room light, blower, radio, parking light etc.
7. Start the engine and hold the throttle at 3000 rpm till radiator fan comes on.
8. After the fan comes on release the throttle pedal and let it idle for 10 minutes.

Fluxuation in electrical power

This is normal behavior in Grand Ams. I've had a '97 and a '04 and both did this from day 1. You'll also notice the lights dim/blower slow down more if you press the brake pedal while idling w/ blower on high and lights on; it's just that the alternator on these cars can't output anywhere near full power at idle. (my '03 S-10 also does this). Watch your voltmeter if you have one, when running above 1200 RPM you should see the system running between 13.5 - 14.5 (usually you just have to eyeball this as the gauges aren't well marked, mine are only marked 8 & 18 - should read slightly past halfway). If you're still worried, have someone check the system for you, many places like Autozone or Advanced will do this for free.
