the small 10A PCM fuse blew on my truck and I noticed that it actually drove better (more power.) Why would my truck perform better with the PCM not working? Or why was it even running at all? Is that just a fuse for the relay or something? It's odd.

The little orange "crankcase" light showed up on my dash on the way to work and since it still started and ran, I left it like that for a few days until I saw that the 10A mini-fuse under the hood by the battery blew. I don't know crap about engine electronics, aynone have an idea what happened? Or why it would happen?

Thanks!
