Start with a tune up, spark plugs, spark plug wires, fuel filter, air filter and that might cure the PO300B code, hope this helps, Gary

97 chevy 1500 sputters at idle in gear can feel it a little while driving no cat. past 2 years run bank1 lean code plugs clean HELP


If the engine is misfiring the check engine light would be on and blinking and the engine control module (PCM) would store a fault code or codes for the cylinders that are misfiring. A lean code will not cause a misfire unless the engine has a vacuum leak most often at the intake manifold gaskets. A misfire code looks like this:

P0300-P0306 for 6 cylinder and P0300-P0308 for a V8.
P0300 indicated a random engine misfire, this can be caused by all kinds of issues.

did the code set for multiple/random misfire or did it set for a particular cylinder or cylinders?if it is random or multiple misfire you may want to check the fuel pressure and volume and for a vacuum leak. if it is a particular cylinder or cylinders then check your coils and also the compression to make sure the engine rebuild is good and something didn't go wrong.

2002 4.3 vortex chevy got a rough idle but smooths out at 1500 rpm and has a miss fire code changed intake gasket


I would replace the spark plugs and plug wires. It sounds like you have a bad plug wire but replacing all of the plug wires and all the plugs should resolve your issue.
