Bad upstream O2 sensor on driver side. Low voltage to sensor sends lean code, which in turn sends more fuel to bank 1, resulting in multiple misfires. That being said, lets me say this as well, take it to a shop and have them look. So many other things can cause this problem from vacuum leaks to looking at it cross eyed. Hope this helps

Po300pd code mean


DTC P0300 indicates random multiple misfires have been detected. Probable causes are:
1. Vacuum leaks, damaged hoses, improper routing
2. Contaminated fuel
3. Ignition system problem(s). Check the ignition module, coil, spark plugs and wires
4. Fuel system problem(s)

When my car is ran on computer is has cose PO300 PD. What does this indicate?


DTC P0300 - Random/Multiple Cylinder Misfire Detected
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.

A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

Hope this helps.

Where is the purge solenoid location on a 1996 Chevrolet silverado 1500 ???? trucks runs bad and I was told it was that or some other vacuum leak also I have code p0300 and p1441 if anyone can help...


A P0300 DTC is a misfire code. The P1441 is a no flow during purge code which has to do with the purge solenoid. With the misfire code present I would say you have a vacuum leak on one of the hoses. The purge solenoid is located in the passenger side, rear of the intake manifold.

Codes 1133-0131-0171-0300


p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.
