Corrosion's probably got a nice hold on your battery terminals - maybe some penetrating oil and tapping it with a hammer
As for the injectors heat soak is a problem on the 2000+ XJs with California Emissions. If you have the two-mini cats in your exhaust manifold and 4 O2 sensors it would be wise to just wrap them and not wait for problems. The mini cats throw off enough heat to boil the fuel in the injectors. Automotive stores have specific heat wrap tape.

Changed the fuel filter. Nothing new. Here is a link to a YouTube video so you can hear it.

I would have to guess that even if there were 00s without them the numbers would be slim. Since a large # of vehicles are sold in California I bet they all have the cali emissions... Or not?...

To be more clear...
Started trails on new property. Got back to creek. Started running very bad.. Here is a link:
Syptoms-many cranks to start (but has a new starter). Finally fires, albeit slowly. Runs ok. When comes up to temp, starts bogging down. Hit the gas bogs right down. Idles ok. Runs ok down highway 10-15 minutes or so.
Have since replaced fuel filter and idle air control. I was driving over some pretty thick brush. Dunno.
I am puzzled. O.o

ive got a 2000 4.0 xj and I have an 02 heater sensor high voltage check engine light on and when the jeep is at idle it runs rough and sometimes itll start to die and I have to rev it up to keep it alive and if I just let it run rough itll build up pressure and pop off the pcv valve line and the air filter hose off the throttle body and smoke will come out of the oil breather. It also has a neutral safety switch light on. has anybody else experienced this any ideas of what it could be? and it died I plugged everything back up and it started fine.

I just remembered the plug on my D35 Diff has a very slow leak, which is annoying since my driveway is angled. Can i just plug it up with a little RTV?
