Hi guys I’m new to the forum looking for help, have a 95 Chevy 2500 454 I’m getting a flash code 36. I’ve done research online and can not find consistent info on the code. From stuff I’ve read I’ve already changed air idle control valve, all the temp sensors, map sensor , checked all vacuum hoses for leaks, check tbi gasket area no vacuum leaks. I’ve also read stuff about Abs speed sensor code 36 haven’t bothered looking at that because it doesn’t make sense why it would be anything to do with abs. I have a friend who is a half *** mechanic and he’s telling me to just replace the ECM because it’s old.. I feel like that won’t solve the problem. Anyone ever dealt with this code or have any insight on what exactly it could be? Thanks
