I have a 2000 Blazer LT w/4.3 vortex V6. Blazer was running fine, but battery went bad. Replaced battery and now the engine is missing. Gave me a P0300 code. Replaced plugs, cap, rotor. Any suggestion on this matter???

 

Welcome to the forum From New York! You should post your question in the tech section if you have not done so already and while you are there search to see if you can find any answers.

Use the 'search' function for "P0300", also look in the Diagnostic Trouble Code (DTC) section.
