rough idle 95 ZJ

[knl25]

My 95 gc 4.0 idles very rough especially when it is in reverse or drive. I just had a tune up and fuel injectors serviced. My spark plugs are coated with carbon, the plug threads seem wet and smell like gas. I took a vacuum measurement off of the intake manifold port and is is -17Hg in park, -14 in reverse and drive. My fuel pressure is at 36PSI with key on engine off and 42PSI with engine on.

Does it sound like I have a vacuum leak? I checked around and cannot locate one. Does fuel pressure seem high also?

thanks for reading

Was this issue present before the tune up or did Jeep start running rough immidiately after?

The tune up was done in the process of trying to get rid of my idle problem.

My inspection of the engine mounts revealed a bad mount on the passenger side. Since the mounts have been in the car for 205K miles, I think I will have them replaced to see if it helps.

Have anyone done this job yourself?
