Dudes. I never understood the Check Engine Light until I finished unloading the parts cannon on my 04 Silverado. I have been listening to others… BIG (EXPENSIVE) mistake. SO here it is, my truck runs great (4.3) and I have a CEL with a consistent P0304. I have literally changed EVERYTHING, BUT the spider. I watched Matts video on YouTube last night as I am totally OVER doing this the wrong way. He discovered a faulty spider in a truck with the same motor as mine. But as I said my truck runs excellent. It should after all the new parts, but I digress. Should I fire it one more time? Really don’t like that plan. What do I test for???
