Well title says it all pulled my SeS code and it's an p0300.
I've been doing some reading on this code and don't know where to start.
My formula starts quickly and seems to run fine. When i bought the car it already had long tubes ORY and magnaflow exhaust. It also threw two o2 sensor codes but i figured that it was proably because of the exhaust/headers. Could this assumption be wrong?

I'm putting together a list of stuff i need to checkout plugs,wires, friend said check into replacing the camshaft position sensor, vacuum leak test, check o2 sensors etc. Any other advice or tip's would be greatly appreciated.

I have done a few searches but mostly reading about people with p0300 their car's start slow, run rough, and die out. Mine doesn't do any of those if there is a missfire it must be at low rpm's because thats the only time the car feels a little choppy.

Thanks in advance.

Seem's there isn't much advice if any on this matter. Just a bump to see if i can get some help.

If that was the only code I'd just clear it and not worry unless it keeps coming back. My car has thrown it a couple times over the years.

If you haven't done it - I would just do the whole nine on maintenance. Fuel filter, seafoam, plugs and wires, coolant flush, and if theres not too too many miles a trans filter. Should make the car run much better. About the o2 sensor codes, if its not causing a big performance issue, its probably the rear ones not being there, or lack of sims/tuning. Clearing the codes won't make that one go away, but a tune or simulators will.

+1 on clear the code. If it comes back, check that all plug wires are tight. I had the same thing and as I was changing plugs, found #6 wire just sitting on the plug.

P0300 is misfire code, not O2 sensor code.

Check the basics first - plugs and wires. This code does not isolate a particlular cylinder, so it may indicate worn components.

Vacuum lines on an LS1? LoL where?
