I have a 07 sierra 1500 4.3
My issue is I have been getting a solid check engine light then it flashes for a bit. Which I believe is a misfire code. I have replaced coil, distributor cap , rotor , spark plug wires , spark plugs. I think it maybe the module on the coil is going bad.
Now tonight on the way home about 10 mi. From home it fell flat on its face no acceleration sounded like it was muffled and starving for fuel the Rpm's were going up but no speed gain and it was barley making it up hills on the interstate. Plz help I am lost what to do
