Where is the MAF sensor located the truck ?
RE: here is no Mass Air Flow (MAF) sensor for your Trailblazer. The 4.2 engines don’t utilize one.

Is there an easier way for me to figure out which coil pack has gone bad in my 2003 Chevrolet Trailblazer other than taking it to the dealership and paying $100 for them to run the test on it?

MAF is calculated by using the MAP sensor and TPS sensor and engine RPM data by the computer.

Not sure what your question is. Use whatever wrench fits the nut snuggly and will not strip it or round it off.

If you just have an engine misfire with code P0300 and you think only one coil pack is bad, just try swapping a new one, one at a time, starting at the front. That one is #1 and is the most common to fail.
