Engine light came on a couple days ago and I ignored it cause I figured probably just an O2 sensor cause my exhaust is fading away but no. My truck that other than my loud broken exhaust runs starts and drives pretty good is giving me an PCM code. Any thoughts? I deleted the code and I'll see if it comes back. Does this mean my PCM is about to kick the Bucket? She's got 177k kms so just over 100k miles. I got a parts truck but it's a 3L V6 so I doubt much is interchangeable unless I swap the entire engine and everything. But if I gotta blow 500 cad$ on a PCM I'm thinking that 3L with 100k km isn't a bad last resort.
