P0300 Diagnostic Code - Random Misfire
Symptoms.
Engine may stumble or miss
Engine may be hard to start
you may notice no issues
Cause
Failing spark plugs or spark plug wires
Bad coil or coil pack
Failing oxygen sensor(s)
Bad fuel injector or more than one
Stuck exhaust valve
Bad catalytic converter
EGR valve or valve passage clogging
Bad camshaft position sensor
Bad PCM or ECM
The Fix
Best first action is a tune up, new plugs, wires, inspect all hoses and wire connections then reset the code. If it returns you will need to narrow it down to a system, coils and coil packs should be tested, catalytic converters for function ( do you smell rotten eggs?). A misfire that jumps cylinders could indicate a lean condition, do you have any other codes along with the 300? this will help clue you in to the source, check valve function to make sure they are opening and closing fully.
This is probably pone of the most difficult codes to troubleshoot, so start with the basics and work your way into the more expensive options, in many cases a good old tune up solves the problem, back it up with a fuel system cleaning and see where you stand.

Engine size
The engine capacity of a 2005 Chevy Tahoe can vary greatly. The engine is usually a 8 cylinder or some are a 6 cylinder. Most are the faster models.
Powertrain control module. The "Brains" of the engine. It receives information from other sensors on your vehicle. It runs the engines fuel system, timing, transmission etc.
The oil pressure switch on a 1997 Chevy Tahoe is located on the back of the engine. It is in the center-rear part of the engine.
You must have been fooling with the distributor. You MUST have an engine scanner to set the timing on that engine. That will then put the cam and crank sensors back in correlation / Time with each other.
look under you Chevy and locate the catalytic converter. Your 02 sensors are located before and after the catalytic converter on your muffler. See 1 or 2?
