Tried searching but couldn't find a direct answer, does an 84 22r carbed truck have a knock senor. The reason I'm asking is because I dicovered yeasterday that mine had one, its not plugged in or anything but it is there and I thought only 22 re's had them. The P.O. put another motor in it before I bought it, said it came out of a 85 4runner just wondering if it was a 22re block .

My 84 22R doesnt have one, but an 85 (EFI) engine/block would.

Thanks, thats what I thought just wanted to be sure. Now I wonder if I have an 22r head or a 22re head

Any idea of the shape of your exhaust ports? Pear shaped are the '85-'95, while round is the early 22r head.

A carbureted 22R does not have a knock sensor. The timing is mechanical. If your engine has a carburetor and there is a wire going to the knock sensor, then it does not belong there and you should figure out what the wire is suppose to go to.

Thanks for all the replies, theres not any wires the sensor is just screwed into the block.
