My 93 isuzu rodeo speedometer is not working


A couple years ago, I had the same problem with a 2003 Silverado. I took the instrumentation module out, took it to O'Neils, handed it over and ordered a rebuilt module and installed it. I wasn't that hard of a fix. 85 bucks. Iassume the speedometer is led/digital. The days are gone when you could simply replace the cable. All computer now.

97 k2500 350 bucks and runs rough at 2000-2500 rpms runs smooth accelerating


There are a few conditions that will not set a code. For example, stumbles are often caused by ignition coil problems. If the problem persists at a certain RPM, could be an O2 sensor problem in closed loop operation not lasting long enough to set a code, or a fuel regulator or injector problem. I would get a good code reader and check readings from all sensors in the circuit (including misfires) to see if you can pin down the problem.

Lost power to engine


Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.

Hope this helps.

Missing


Sounds like a load miss. Chk plug wires for deterioration and or cross firing. Wires should not cross over each other. Worn plugs load wires causing increase spark out put increasing cross firing potential

I just had the same issue with my 88 xlt w/351 W it wound up being the MAP sensor and the timing. I would check both of these and see if it solves your issue.
