cel light comes on

[joshmk]

so when im driving my 93 gmc sonoma 2.8 5 speed, sometimes the cel light will just come on and then turn off. I just baught the truck and it is running right so i think its just a sensor or something, but my first queshtion is, it is a obd1 system correct. also on my old car i was able to use a jumper wire to make the computer go through a series of test and then flash out the codes. can i do this with my gmc and if so how?, and last queshtion is where can i get a obd1 scanner that is cheap but a good buy, not 300$ but more than 60$ a half way decent one.
thanks for the help guys.

You can get the code scanned at autozone for free.,... Or you can paperclip the 2 top right holes of the ALDL to flash the codes to you. Yofu can pick up a cheap scanner at most autoparts stores for about 50 bux.

hey guys, thanks for the help it was pretty much the same thing as my last car but different ports, i havnt pulled the codes yet, but it is weird because whenever im comming home at night on the same stretch of road almost in same spot in 4th gear the light comes on, usually when the truck is getting to operating temp, so ill pull the codes and get back to you guys, thanks for the help!
