Question? I just replaced my rear main seal along with all of the engine mounts. Seems to be running ok except for a rough idle (only at idle). Does someone have a vacuum routing daigram? May have swapped a vac line by mistake. Also have a P0137 code that popped up (rear O2 sensor), would that cause a rough idle?

Thank you.

time to get your OBD boxes fixed so you can get more specific codes. If the rear O2 sensor is slow, then it could be that the car needs to be driven to clean it off.

A bad vacuum line can cause over-rich conditions. Most of the confusion will be three vacuum lines at the turbo and boost controller. You will also want to check the fuel pressure regulator line that routes to the vacuum tree.

I do not have a good, complete diagram for a 1995 T. It must be year specific.

Thanks, I actually have an OBDII reader. And that O2 sensor light has been coming on every couple hundred miles, I'm going to just replace it...again.
As for the vibration at idle, I replaced every mount when I did the rear main, although I didn't torque any of them, I probably over tightened em. I'm going to go back and set them to the correct torque. I cranked down the subframe mounts too, probably too tight. I'll re-torque those as well.

Some of the generic O2 sensors don't last long. At a minimum, get Bosh direct fit, no wire splicing!
