Just an idea that may or not fix it but it's a cheap and a good idea anway... go buy a few bottles of gas line antifreeze and add one now and one at your next fill up and see how you make out

My 2000 Isuzu Trooper runs well. My problem is once I get above 2000 RPM's my engine light flashes.


That means there is a big problem whenever it flashes. You need to get it in and get the code asap. When it flashes, they call that a major issue. Be careful and go asap. Autozone checks for free but you probably need a mechanic.

My 1997 Isuzu bighorn (trooper) appears to "miss"


When is the last time a tune up was performed on the vehicle? I would get some amsoil engine foam, and use it as described. Also get some fuel system cleaner and use that as well and go from there.
Thank you,
Lee

How to know your automatic transmission is working fine


Auto. Transmition when giving trouble will not change up until R.P.M. has gone over 2500 rpm. Should should change up between 2000 and 2500. When changing it down (pushing accelerator to the floor) it should do this imedietly. Isuzu Troopers have a power button on the console between the front seat's this is for trailer pulling and when it is on.(power light on in Dashboard) then it takes more R.P.M. to change up allowing for trailer weight.

1992 isuzu trooper 3.2 DOHC 4X4 LOW IDLE GOES UP AND DOWN 750 RPM TO 1500 RPM


I had the same trouble with my 93 Trooper.

I went on a sensor-changing spree.

The one sensor that fixed this idle problem was the throttle position sensor.

You can get one here.

Throttle Position Sensor

It's very easy to change, and fixes the problem instantly.

Good luck.
