Plese help! My check engine keeps comming on, it appears to be random.
The light will usually go off when i step on the break pedal hard. It does not seem to affect it runability as i just passed the emmissions test. I acts like it is a sensor of some type. I have a 1991 Isuzu p/u 4x4.
Any suggestions or ideas would be greatly appreciated. :confused:

Go to your local AutoZone and they will pull the code for free. Let us know what they tell you and we can give you a little more help.

Good luck, Rob
