Had the same code thrown along with a maf error code. Took weeks to figure out. Ended up being a short in my fuel pump wiring inside the gas tank that was throwing all the codes. Also had bogging issues. I would check all your harneses.

If you do replace the knock sensor it is also a good idea to do the harness sensor at the same time.

don't bother replacing the knock sensor. ditch it entirely and plug it up with a diode. There is information on how to put a 1mhz 1ohm sensor in place of the knock sub harness. this will alleviate that as a problem.

If your engine is going to knock, it's gonna knock. That sensor isn't going to do shit to save it.

I forgot to mention that I already knew that code 34 = knock sensor. Harness is beyond shit from the previous owner, I didn't notice it at first but the more work I do on the car the more splices and electrical tape I find

Thanks for the help guys looks like some electrical work might be in order and deleting the knock sensor.

Found this as well.
"Solid motor mounts/worn broken motor mounts will/can make a solid connection to your chassis causing extreame vibrations at idle and low rpms. Normally the stock mounts dampen this.

Our knock sensors should pick up on these vibrations and retard timing. This will make your car "slower than it was."
