Question about 2001 Chevrolet Blazer
That smell is a dead give away. your conv. is clogging when it gets hot, and you have a bad oxy sensor. the reason for the converter is the 4door is more popular, so they more relacement parts for it. If you go to your local exhaust shio like we have at home, they can save you a ton on price and parts, and they will make it inspection safe for sure. after you get the work done, make sure you add a can of SEAFOAM to tank, and every 5000 miles to keep emission and fuel parts clean. the ethanol gas is causing terrible problems, and for some reason, especially GM vehiles(they don't know why yet) good luck

A code P0300 may mean that one or more of the following has happened:
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders ( spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open
