[86CL-86LS-88LSmontes]

Hi Everybody,

My name is Matt. I live in the Northeast and I own 3 Chevy Monte Carlos.
I have an '86 Monte Carlo CL (White, Blue interior, pw, pl, T-Tops, 4.3V6), an '86 Monte Carlo LS (Dark Blue, Blue interior, bucket seats, floor shifter, 4.3V6) and an '88 Monte Carlo LS (Light Blue, Blue interior, pw, pl, ps, 305V8). My '86 CL is waiting for a rebuilt transmission, the '88 LS is in awesome shape inside and out. It only has one problem....frame is of course gone on one side. It is only in the flat area that goes along the gas tank. The frame is fine over the axle. My reason for annoying you today is my '86 LS. I have had many g body cars. At least 4 to 5 Olds, and 5 Chevys. I have never had a problem with getting computer error codes from any of my cars. The engine light goes on. I follow the required process to get the codes and I get....Nothing. The first time I tried it was 2 days after I bought the car. I have owned it for almost 2 weeks now. The first time, I got the normal flash of 12 3xs. I then started to get the beginning number of the first code and the check engine light went solid and stayed that way. I turned of the ignition, unplugged my key, and replug the key and then turned the key to the on position without starting the motor. It started to flash the second 12 and then went solid again. I have tried numerous times since then and all I get only sometimes is one flash of the light and then it goes solid. I am stumped. Does anybody happen to have any ideas? They would be greatly appreciated.

-Matt
