Miss at Idle

[rrgrassi]

Hey Guys,

My baby (82 300D) has developed the shakes, after reaching normal operating temp, she seems to miss at idle. You can see the front end of the car rocking as if she were a chevy 350 with a radical cam.

When she starts after sitting over night, the idle is smooth. After driving a while, when I come to a stop, she shakes like crazy at idle. No missing under acceleration, though. All research I have done leads me to believe I have an injector acting up or air being sucked in a hard line. I do not detect the smell of fuel when running, or shut off. The number 3 injector does not have the braided return lines. Looks like the PO used regular vacuum line instead.

I did notice that my left engine mount is torn and I know that will accentuate the shakes.

I just wanted to see if my diagnosis sounds right. Everything else seems to operating as it should.

Thanks!
