No a knock sensor can not make a misfire. Check the coils, plugs and fuel pressure .The random misfires are cause the knock sensor to throw the code.

cylinder number 2 misfire bad plug bad coil swap them with another cylinder and see if it changes p0301 is number 1 misfire p0306 is number 6 they also crack cylinder heads so swap around the coils first

It is misfiring. It likely needs a tune up. Have it scanned. This will tell you which cylinder is misfiring. Recommend replacing the plugs and wires

The coils are the next place to look.

Start with a tune up, spark plugs, spark plug wires, fuel filter, air filter and that might cure the PO300B code, hope this helps, Gary

When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.

Ex. P0401 means there is misfire on cylinder number 1

P0400 is a random misfire detected.

If you take it to an Advance or Autozone they will usually scan if for free.

By the way, if you used cheap plugs instead of platinum plugs that could do it too.

Hope this helps.

sound like a bad coil pack on the number 6 cylinder
