Need some help with check light

[smlarkin]

Hey everyone I am in some need of help. The other day my check engine light came on so I plugged my reader in to get the code and it says p132b manufacture controlled ignition system or misfire. I have googled the code to see if I can get some help with what this means and how to fix it but all I can find is something about the #code being a turbo problem but nothing about the manufacture controlled ignition system or misfire. The truck seems to be driving as normal, nothing is different when driving. Please Please help I'm stuck on this one and don't know were else to look and fix the problem.

Doing a search on here, I found this thread sounds like a good place to start.

Thanks for the response. I looked at the thread you gave me and it helps. the thread says may be due to an exhaust leak, how do you check for that other than just the smell. being a straight pipe it is going to make it smell more than before too, right? I know these code questions are always hard to get a response and I really thank you for the help.
