Flashing engine light

Asked by Jul 12, 2016 at 10:27 AM about the 2005 Chevrolet TrailBlazer LT 4WD

Question type: Maintenance & Repair

I have a flashing engine light that comes on when
the motor is under any kind of strain. I've scanned
it and it's reading P0300. Multiple cylinder misfire.
I've replaced the plugs and it still exists. It has a
rough idle but it seems to be running a little better.  
I'm kinda at a stuck point. Any ideas where I should
try next?

Professionally clean the injectors, run a fuel pump pressure and flow test.

Also have mechanic check for a partially clogged catatlic converter.
