Anybody know this part?

Looks like the # is 0356914312. The connection is made next to the cps. I found it hanging lose today and wondering what the hell it came from.

It looks like the little connector that goes around one of the ignition wires.

^exactly. Should need it for the tach to work I think.

That is the sensor for the Cylinder ID signal on an M20B25 engine. It should be on the ignition wire for cylinder #6. The purpose of the sensor is to tell the DME at what position the crank is so that the DME can fire the injectors sequentially rather than in parallel. The engine will run okay without data from that sensor, but fuel mileage and performance will suffer.

Holy shit that explains a lot. Got
My idle down to normal but it sounded like I had a misfire.

Isn't it for cyl #1?

Nope, #6.

For the OP, my guess is that a PO went cheap and replaced the ignition wires with a set meant for an M20B27 engine. Which doesn't have the Cylinder ID sensor. The best thing to do is to get the right ignition wire set.

Anyone have the correct part number for an m20b25
