[GTJake]

what parts...?

[CoraC143]

what kind of parts?

talk to Ryan at BlueDogJeep.com

[JordanWalk193]

small things like plugs wires o2 sensors

[MrMindless]

oxygensensors.com for the O2s, I like Advance for the rest.  smike loves himself some Auto Zone.  Dunno where the rest of yall go.

[JordanWalk193]

found out the reason the jeep was running bad was because it had a really cheap 160 degree thermostat...damn used cars

[GTJake]

haha, nice

[JordanWalk193]

how hard is it to put an o2 sensor in

NU WAY AUTO PARTS...

[GTJake]

o2 sensor is just like a spark plug

[MrMindless]

except with a pigtail that gets in the way and it\'s usually rusted in BADLY.

PB B\'laster is my choice  for rusty things.  bang on the bung with a hammer to help break it loose.  you may have a fun time with clearances, and the plug is usually a pain to get at.  I usually cut the pigtail off the one I\'m removing and do it with a deep well socket, and install the new one with a LOT of anti-seize and an open end wrench.

so the guy that owned the jeep before me did a lot of damage to it. he ruined the exhaust system and i dont even have the wires so ive got 1 o2 sensor instead of 2...he also put in the wrong type/size spark plug. just changing the plugs and distributer cap my gas mileage has gone up from around 10-11 to about 18 mpg. sweet!

[MrMindless]

nice!!

[JordanWalk193]
