6.5L check engine light
I have a 95 6.5 suburban with a #9 resistor in the PMD and when im driving down the road and holding a steady speed and rpm the check engine light comes on. If I'm on cruise or just normally driving the light comes on I let off the pedal for a second or kick off cruise and the light goes off. Any suggestions would be helpful if someone know what is going on would be appreaciated.

His is OBD-I auto part scanner won't work, he will need to jump pins A & B in the diagnostic port with key on and count blink sequence of the CEL/SES ligh to "read" the code, or go to a shop that still has GM tech 1 capability, anybody with a OBD-I would be well served to get this for their laptops Engh Motors - Makers of GMTDScan, the PC OBDI/ALDL scan tools for 1994-1995 GM 6.5TD trucks.

If they have one I doubt they do, and common "readers" if you can find one are not much more than a paperclip with a light bulb held in plastic body that blinks. You pretty much to do any real time diagnostics use a tech 1 tool or the laptop software I linked to before.

I recommend you start your own thread as it is easier to manage diagnostics vehicle by vehicle vs. multiple vehicles in 1 thread.
