Where is the knock sensor on a 91 Oldsmobile aurora 4.0v8

Can be anything from bad gas failing sensors needing tune up to failing engine start with hook up and scan trouble codes then start checking fuel/electronic components

According to my info, you don't have a maf sensor. You do have a map sensor, I'm not sure if you miss-spoke or what?

On the right side of the vehicle is the oil filter box next to the filter is the oil pressure sensor.---------------------------------------------------------------------------------------

You can use regular fuel. The ignition system on your vehicle is controlled by the computer which will ****** the timing if low octane fuel would cause spark knock, also called pinging. Even high compression late model cars can run on regular fuel because of the computerized knock sensors. I doubt that you'll notice any difference in driveability or performance on regular fuel.

knock sensor is usually located on the block or the cylinder head so it can listen for knocking and has a wire or wires leading to it from the harness..

EGR Valve is located on the top of the engine and has vacuum tubes leading to it from the EGR solenoid.

its under the intake manifold, good look replacing, luckily i have had to replace on on any of my 3 aurora's that i've owned, knock on wood.
