Check TPS voltage at idle, should be around .5 Volt. My fix for that situation was an LS7........

So, you didn't say what the code(s) are, what are they and what have you done? If you do not have an 82 GM service manual, GET ONE! You will need it and it is a great manual to have.

Do you mean there are no codes at all or you are getting code "12"? If it is the former could be leaning towards a bad ECM.

Just in case you don't know, you read the codes with key on engine off. If you try reading the codes with the engine on you are in field service mode and flashes are something different.

Am I assuming correctly that you have an 82 GM service manual?
