What are the misfire counts for EACH INDIVIDUAL CYLINDER?

Does your scan tool have the ability to provide cylinder-by-cylinder misfire codes? Many consumer-grade junk tools LIE about misfire codes. They display "P0300 random misfire" when the REAL code might be "P0307 misfire on cylinder 7" for example.

Misfire promotes a false LEAN O2 signal, so it's not surprising that the fuel trims go to rich-command to try to correct the false lean signal. Based on your long-term fuel trim, I bet the misfiring cylinder(s) are on Bank 1.

When my truck starts running rough at idle, it's time to change the intake gaskets. I think I have a warped intake manifold.
