Check engine lite came on and AutoZone read the code which said there was a problem with the knock sensor. Where does the knock sensor wire terminate so I can simply check to be sure it hasn't somehow been disconnected?
Should be nomore than 5 olhms from center of knock sensor to ground. these sensors have certain resistance values and are very sensetive.

Make sure you are not over torquing it. if you screw it in to much, it will give false readings and if it is not screwed in enough, it will also give false readings.
There's a delicate balance to be known and, if this sensor is over torqued or, not torqued enough, it will malfunction.

there is a large evaporative leak. keep away form ottozoo, they dont have the brain power to actually diagnose a light bulb., their job is to sell parts., if they sell you the wrong parts tough.Take it to a qualified repair shop that does a lot of GM work or the dealer.

code po300 is a random misfire code do a tune up plugs, wires etc and clear the code it should be fine
SOURCE: p300 engine code replaced coil,wire,control module
P300 reads as: 'random/multiple misfire' which usually means all cylinders are misfiring intermittently. Suspect a defective crankshaft/camshaft position sensor or weak fuel system pressure. If only one cylinder is misfiring (check by sliding a test light probe [make sure the ground lead is clipped to the engine securely] between each plug wire boot and it's wire at the distributor/coil block to short out that cylinder's spark. The dead cylinder will not change when it's spark is killed. Try a new spark plug first, then test that cylinder's compression if no help. You could have a bad valve. If the old plug was wet with fuel, the injector is probably doing it's job. When this cylinder runs again, that may clear up the backfire problem. Hope this helps!
