needing help with my 95 blazer. its throwing the code for knock sensor bank 1 i replaced it still threw the code. i checked the wire it is fine. and i found a wire for another knock sensor but cant find the sensor it self. also will the po300 code be thrown for a bad tps?

 

usually there is a sensor in the drivers side head inbetween the exhaust outlets in the head - other is usually located in the back of the riders side head

 

A p0300 is exactly that....... A general misfire affecting all cyl.....and given the nature of the fuel systems I would start by doing a fuel pressure test!!!! Then , if that all checks out, ? Go thru the secondary ignition system......very very important that u use delco cap,rotor,& plugs!!!!! As far as wires ac delcos or autolite premium only......if u do a search u can find several threads regarding the p0300 & the proper testing procedure for your fuel system....goodluck, and remember u are in the right place for all the help u will need !!!!
