idle idle idle sputter idle
 

Yep. My st00pid idle problem got the better of me so off
went the ZJ to a local wrencher (Sooner Auto). Nice people
with a lot of experience. They checked the injectors, compression,
fremble valves, and all were within spec. Biggest problem was my
fuel filter was clogged .....mumble.... I could have checked that
myself but since acceleration was fine it just didn't cross the
ol brainpan. Heck, I even have a spare in the garage. Must have
gotten a tank of crapoline or something is growing in the fuel tank.

(not sure, but does a gas tank grow algae like a diesel tank does?)

Anyhow, they will run solvent through the rail. The stuff you
can't put in a tank cause it will dissolve certain types of plastic.
Hope that fixes the problem cause I'm running out of things to do.


..... and being _super smart_ today I decided to ride my 10speed
back home. Got here and it felt like I had a horse sitting on
my chest. :( .getting older sucketh. I seriously need to get
more aerobic exercise, lifting weights alone isn't cutting it.
Strange thing is I can hike for miles with no problem but the
old bike beat the snot out of me.

I guess anything's possible, but it sure doesn't make much sense that a plugged
filter would be more evident at idle than on acceleration...

I'm bettin' they haven't found it yet. Sorry. :-)

Re: idle idle idle sputter idle
 

That happens on my mechanical pump system sometimes just before all heck
breaks loose. When my rpm come up, so does the pump flow and it will
push by the blockages.

I suppose the power could drop to the electric pump at low rpm causing
the same effect maybe?

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.
