That was my thought as well, but it is running a lot better now.
They also ran heavy duty decarbonizing/cleaning stuff down the injectors
to clean out carbon buildup. That may well be the cause of my rough idle.
The ZJ was running way rich due to a cracked exhaust header and weak O2
sensor. Oddly though when I had the exhaust header off the valves looked
real clean, only the intake rail had some oil/crud buildup which is your
usual CCV caused buildup.
Even if it didn't fix the stumble it sure brought back some noticeable
power. For right now it idles quite a bit smoother. Not perfect, still
has some vibrations, but no where near what it was doing.
On the bright side they did fix a few buzzes under the hood, a hose
that was rubbing, and spotted an interference between the ABS pump
and my supercharger. That last one I'm afraid is due to a busted
motormount isolator. Jeep only sells the damn things as a whole part
and there are no aftermarket parts. :( Oh well, it's a Jeep thing
and "they" understand.
Gonna have to let the motor cool down and put a prybar on the mounts.
Should be easy to tell and fairly easy to fix. Wonder if I could mill
a new mount out of poly? Or more precisely have the local plastics
shop do it for me. Its only a glorified rubber donut.

Dunno.. At boost levels the Kenne Bell boost-a-pump module ups the fuel
pumps voltage and by that the pressure, but that's only when the rail goes
above 2psi. Othewise it should stay stock.
Overall performance had been going down along with fuel milage. First
thought was vac leak, but a few passes with the propane wand didn't find
any leaks.
Checked and cleaned every single connector also. Even checked the sparkplug
wires for crossfire or leaks and the cap for arcing.. Spent so much time under
the hood I figured it was time to let another set of eyeballs look at it.
That and I don't have the equipment to properly clean the injection system.
Guess my next project will be to install some more electronics. A O2 sensor
and electric sending fuel pressure gauge.
