This isn't a how-to video. Instead, you're gonna ride with your boy as I troubleshoot a misfire problem in this blazer which runs terrible and sets a P0300 code almost immediately after starting. A how-to isn't possible because the tools needed to read live misfire counters and fire the injectors are outside what the typical diy'er such as yourself will have access to. Knowing which cylinder(s) is/are misfiring is critical to an accurate diagnosis because there are other things not related to spark/fuel/compression that can set a p0300 in these trucks. If and when the time comes where I can show crank sensor/distributor related p0300 troubleshooting I'll be sure to post about it.
My thexton 404 is still alive and kicking years later.

P.S. Sorry to see that you guys are doing so bad that you have to resort to lies and deception to pay the bills. How the #$%@ do you sleep at night?
