Re: More Questions
Normally when I see a disconnected canister, that means the purge valve
went bad.
I noticed you mention you have it hooked up now. I would recommend you
test it.
If blown, the canister purge valve will effectively shut down the PCV
system and cause lots of oil to spit into the air filter. It will also
make the idle rough and erratic.
To test it have the engine running at idle and pinch the line from the
canister to the PCV line closed. If the idle changes, the canister is
dead.
The canister is only supposed to be purging when the engine is hot and
at speed. The purge signal is a ported vacuum source routed through the
CTO valve.
The canister also has an air filter on the bottom. CT sells them for
about two bucks. Getting the first one out is a bear, it will need to
be dug out with a screwdriver or hammer and chisel like mine. The new
one just tucks back in.
You really don't want the EGR to open until the engine is 'really'
warmed up. That TVS holds the EGR closed until the air filter has
warmed up enough.
Maybe ask CT about one from a 91 YJ? Or one from a 86 CJ7? These both
have the 4.2 engine.

Yup it sure was the idle had picked up 100 or so RPM and it had that

I took it off today and it is packed up solid I'm waiting for a new

Now that I have had a chance to drive it since doing the Nutter and
adjusting the idle screws I do notice a slight stumble went I start
out from a stop...... What could be causing this?
Thanks as always.
