2004 Silverado 1500 misfire issue
I have a manual 2004 Silverado 1500 4.3l and I seem to be having a reoccurring misfire issue. The truck occasionally (not everytime) will struggle to make it up hills when I’m accelerating. It appears to lose power and the stick shift starts violently shaking. Occasionally it will cause the check engine light to start flashing for a few minutes as well but not every time. The issue seems to come and go.
I recently took it to a mechanic and they put all new plugs, wires, and replaced the distributor cap and that didn’t solve the issue and I took it back and they installed one new o2 sensor for me. The truck ran fairly well and the o2 sensor seemed to have solved the problem for a few months however now it’s starting todo the same thing again. I’m not sure what to look into fixing next.
Any information would be greatly appreciated! Thanks
