Sometimes this code po300 chevy suburban will be set in addition to other codes such as P0301 which means that there is a po300 chevrolet misfire on cylinder 1 (cylinder 1 is the number one cylinder when looking at the firing order. It is generally the forward most cylinder on the engine.).

Each cylinder will fire a spark plug, one after another, in a smooth po300 code chevy and continuous manner. The spark plug fires a spark, using the flammable fuel air mixture, and sets fire to the fuel. The fuel then releases energy that powers the crankshaft, which must continuously turn smoothly as the car is moving. If more than one cylinder misfires, this will increase or decrease the revolutions per minute (RPM) of the crankshaft. If that increase and/or decrease is more than 2 percent, the Powertrain Control Module will store the P0300 trouble code. If the percentage of the increase or decrease in revolutions per minute (RPM) is between 2 percent and 10 percent, the Check Engine Light will come on. If the percentage of the increase or decrease in revolutions per minute (RPM) is greater than 10 percent, the Check Engine Light will blink on and off, as to alert the driver of a more serious misfiring problem. The P0300 trouble code indicates that there is a misfire in random or multiple cylinders. What causes the P0300 code?

I read it and it was a P0300 Random/Multiple Misfire. I had experienced a slightly rough idle previously (nothing serious) and had been unable to track it down. I replaced the PCV valve as a course of standard maintenance and it seemed to help get the idle back down, but still slightly rough. I also replaced the spark plugs and plug wires, and replaced the alternator on warranty for an unrelated issue. After I got the check engine light, I started doing some more diagnosis with a bluetooth-OBDII reader which is when I found that I had misfires only on cylinders 2, 5, 6, and 8. Since it was on separate banks, I could find no commonality of items to replace, so I tried the following things. replaced coil pack in cylinder 2 because it had the highest misfire count, no effect replaced the EGR valve, also with no effect. did the carb test to look for vacuum leaks in a few places on the intake manifold with no results unplugged to MAF to see if the idle improved and it did not (although I didn't try a load test with the unplugged MAF.)
