2001 Chevy Tahoe Code P0300

Chevy Tahoe P0300 Definition P0300 is a general and random misfire code, whi

ch means that the code is not going to tell you which cylinder is causing the misfire. Something is causing cylinders to misfire at random, which is a lot less cut and dry than a cylinder specific misfire code. See Also: P0300 Chevy OBDII Code

Chevrolet code P0300 indicates that one or more cylinders are experiencing m

isfires. A misfire occurs when an insufficient amount of fuel is burning in a cylinder. The efficient burning of fuel is essential to engine operation as the combustion of fuel is what provides the energy to power the engine in your Chevrolet.

This was all last weekend, but after I fired it back up, same problem, same

consistency. So I borrowed a code reader and found P0017 and P0300 codes coming up. P0017: Cam/Crankshaft Pos. Correlation Sensor B - Bank 1. P0300: Random/Multiple Cylinder Misfire detected.

This Tahoe was setting a P0171, P0174, and a P0300. We all know the P0300 is

misfire code which is probably being caused by a lean condition that set the other two codes. The P0171 and P0174 code set criteria is that the long term fuel trim cell must be above 23% for 6 seconds. Three things came to mind when I saw these codes.

Ran diagnostics. OBDII codes P0101 and P0300 returned. Codes continuous. Ser

vice Engine light comes on during operation; will go off on its own. Reappears at random, for short intervals. Truck has had coolant leak for about a year; codes present during time of leak. Takes about 1 gallon of antifreeze every three months.
