Question Possible Fuel Filter Issue

Ive been having a problem with my 07 Wrangler. But on top of the occasional bad idle when at a stop, Im having trouble at low RPMs while in 1st or 2nd gear. Its kinda like a studder, I can feel the Jeep bob alittle like its not getting a constant flow of gas like it needs too...... Was told it could possible be my Fuel Filter being clogged.

I think I have managed to find the Fuel Filter, Im not 100% sure but I think it is located under the back seat drivers side. There is a black box about 12" x 4", has two hoses going into it. I know for sure one is coming from the fuel tank. Ive been trying to look up fuel filters online and havent had any luck so far trying to find one for a 07 Jeep Wrangler. Is this even the problem?? Id rather not go to the dealership so they can try and charge me 100$ for a diagnostic check. I love working on my jeep and if there is anyway I can do this on my own Im going too. Only thing is I need some advice from one of you high speed mechanics.

That's the Evaporative Canister. Your fuel filter is in the fuel tank. They have to do "diagnostics" first before the tank comes down to replace the filter. I would go to the dealer on this one or a shop that can diagnose the problem. Could be alot of different things.

I just got a diagnostic check from a Jeep Dealership and they told me it was an EGR Valve issue. Will basically cost me 400$ for parts and labor, I was looking online for a EGR Valve for a 2007 Jeep Wrangler and it was only around 65$. Ive looked under my hood trying to find it with no success, any help will be much appreciated. Im hoping this is a job I can do myself once I get the right parts to fix the problem.

depending on your automotive knowledge and tools, replacing an egr valve is not to hard. i would say the best thing for you to do would be go to your local library that has internet and use there online alldata. alldata is basicly a program wich will show you exactly how to replace the egr valve. it is the same program shops use and pay alot of money for, but the library has it and alows you to use it for free. if your library offers this online free program i recomend you go take a look at it. if they do not i recomend you buy the chilton manual for your jeep.

it is hard to diagnose something online for somebody when the vehicle is not present for the mechanic to look at and both of the 2 things i mentioned will also help you to diagnose problems once you have a general point at wich to start.

Thx for the advice, much appreciated. I went to the library but couldnt find anything on an EGR Valve, and the Chilton Manual for an 07 Wrangler is sadly 400$ . I was able to find the EGR Valve on the passanger side right up against the fire wall under the hood. It will be tight but workable. Has anyone ever changed one before, it seems simple enough but would like to make sure there isnt anything special that needs to be done besides some gaskets and afew bolts. Any advice on the matter will once again be very much appreciated before I dive into this project.....

i honestly have not replaced one on the jeep yet, but i am a mechanic and have replaced many of them in the past on various vehicles. as long as you have the right tools for the job, again it is fairly simple to do.

did you check if your library had alldata online? if not they probably has something pretty simular too it. it would be vary helpful to you. it would also give you step by step instructions on how to remove and install the EGR valve. as wellas tell you the exact tools you would need.

Well the Libraries around me dont have alldata but they do have an auto repair portion, which had 07 Wranglers but had nothing on an EGR Valve sadly. What kind of special tools would I need..... Im in the military so I go on post and they have whatever I need at the shop along with lifts. It looks like it just comes right off after you take the bolts out..... Just let me know if im missing something.

were are you located? if you dont have a tool i am sure the auto skills center on base would have it and if they dont they will get it for you. but i honestly think you could probably tackle this job.

Figured I would share this, just went to the car wash and hosed down the entire inside of my jeep. I put a trash bag over the CD player and all but it worked very well.

I am in the Army, Meade is near DC which is about 90 minutes from me. Wouldnt mind goin either to Meade or Belvior since Im from VA originally.

Davem: You should know they dont have much of anything under warranty after 35k miles, Ive driven my Jeep alot and I am def over 35k miles.

Just a quick review on me changing out the EGR Valve for my 07 Wrangler. There is only 4 bolts but with the EGR Valve being in such a tight area, (next to firewall on passanger side) it took me roughly 2 hours to finish replacing it. The easiest way to losin and tighten the bolts is from underneath with a ratchet wrench, takes alot of patience to slowly losin/tighten the bolts. Besides that it wasnt a complicated job and the end result is the bobing has stopped completely and also seems to accelerate alittle more firmly.
