Need help changing Spark Plugs in 2003 Wrangler, 4 cylinder, manual

sportyceejay08 · 02-27-2009, 01:45 PM

I'm new to spark plug replacement and have run into a few roadblocks... there is something directly above one of my spark plugs that isn't allowing me direct access to it. i really don't know what it is and i'm not sure i can remove it and put it back right; so i'm hesitant... can anyone help with what it might be and if it's ok to detach or is there a way around it?? thanks so much!!

I believe your speaking of the air filter? Plastic tube connected to a plastic box that runs across engine to throttle body?Welcome to Jeep Forum!

yes, i know it's the air filter on one side, but it seems to be going across above the spark plug and then connected to something that is spring loaded... ?

I have the 6 cyl. but are you speaking of a flexible round tube (about 3"in diameter)that goes over the engine and then elbows back down into a metal fixture(throttle body) with a clamp securing it?Also there will be a throttle cable coming into the throttle body.

i'm not lookin at it right now, but that does sound right. the thing that concerns me is that it looks like there's a spring-loaded something right there at the joint where i would think i needed to disconnect it to get to the spark plug...

I think you should wait till someone chimes in with that specific engine.

you should purchase a Haynes manual, it is extremely helpful when doing anything on your jeep. I am not a salesmen for Haynes or anything. I would love to help out some more but I have the 6cyl so I can't really be too sure what you are looking at.

i'd love for it to be that easy, it just looks like it's not. but maybe i was looking at the wrong angle. i was looking to detach right above the spark plug; but you're saying i should go from the air filter cover which is further to the left on mine...? hmmm, i'm wondering if they're totally differnent between the 4 & the 6. wish i could take a picture and put it on here...

Yes you definitley need a manual.The best would be a FSM (factory service manual)for your specific year and model.You could also by a cheap repair manual at any auto parts store.

If you're not talking about the air filter tube are you talking about the coil rail??? Go to www.4x4xplor.com and see if their spark plug write up matches yours. That website has answered countless of my questions. Good luck.

well, thanks for your help

i do appreciate what you've offered so far... i'll try to find a manual
