What is a 'Knock Sensor''?

The knock sensor (KS) are commonly found on modern injection engines (carburetor engines do not have them installed), but NOT all injection engines use a KS. It is a sensor that outputs a small electrical signal on detecting 'engine knock'. Its related to ignition timing and fuel detonation within the cylinder head. On receiving a knock signal, the ECU (Engine Control Unit) will temporarily adjust (retard) the ignition timing to prevent the condition.

Some engine systems with a KS can detect engine knock in an individual cylinder. Timing for that cylinder alone will be retarded by the ECU until knock ceases.

So basically, the KS is used to stop the engine detonating (destroying) itself when the engine is running.

not if you're using an auto manifold.

Auto manifold makes it totally plug and play.

Well you want below 90K I would look for like 55K miles or less but thats just me. Anything over 90 you dont have a clue how it was driven what is the matter with it various different things.

Call hmotors for a y8 head. Should be decent pricing and you know it'll have low miles.
