I bought a Jeep in Texas and am trying to get it approved for emissions in CA and got a checklist from the shop of things I need in order to pass. I have the original I6 258/4.2L but installed an HEI distributor instead of running the original setup. What I'm really struggling with is what the...

Hello Everybody, I appreciate everybody's help on these forums. I have been able to solve any problem with my jeep for 2 years using the forums until now. I have a 95 YJ with a 4.0l engine. My current problem is that idling the RPMs are inconsistent. When it is first turned the jeep on the RPMs...

First time post and first time Jeep owner. I have found so much great info on this site, but one common thread is how quick everyone seems to be to dump their emission vacuum lines. As a resident of CA, I really need these vacuum lines working properly for my registration. I have tried...

1985 Jeep CJ Loredo 6Cyl manual trans. Passed the emissions portion but failed SMOG due to EVAP leak. It leaks gas with a full tank so I suspect I have broken lines or seal somewhere. Stops leaking at 3/4 tank. I don't have the tools/place to work on cars anymore so I'd rather take it to a...

We have a 2012 Wrangler Unlimited Sahara with the Altitude package. The check engine light went on and came off a few times, but now stays on. It no longer says Econo when driving and when I had Auto Zone read it, the error code said something about the catalyst. Does anyone know what might be...

Lingering idling/stalling problems with my 1979 CJ5 led me to replace my Carter carburetor with a Motorcraft 2150 knockoff. I received the new carb this week but before I switch it I'd like to do some simplification and house cleaning under the hood. I understand that many of these steps will...

Hello All, I just moved to Texas and have to pass an emissions test. Unfortunately, it's one thing after another trying to get the check engine light off. I'm getting a recurring P0432 Code (Main Catalyst Efficiency Below Threshold Bank 2). The odd thing is, I only started getting this...

All, I just wanted to share what I found through trial and error and lots and lots of searching this forum, other forums, and online in general. I've had EVAP (Evaporative Emission System) leak error codes (P0455, P0456, P0457 or the GAS CAP message) multiple times over the past couple of years...

Hey everybody, I have an 89YJ and recently just went to get my Emissions done and failed. It stated my Carbon monoxide reading was to high. I have an OEM refurbished Carter 2 barrel on right now. I have had it on since 2010, and I did pass a couple times before. I am having trouble starting...

Hi, I purchased a basket case jeep ('83 CJ7 Laredo 4.2L I6 T5 transmission) and have been slowing piecing it back together totally stock including emissions. I am probably a minority wanting this to be back to factory (including all the vacuum lines) and as such, I am finding it difficult to...

Greetings everyone, This may be my first post, but I’m not new to Jeeps or to this forum…I’ve been lurking for years. I have been researching engine swaps for some time now and have a plan for what I want to do. Thanks to this forum I feel reasonably prepared to tackle the project. I have been...

I've got a 2003 Jeep Grand Cherokee with 160,000 miles on it. The problem I have is I've got a bad catalytic converter, my mechanic said that my Jeep is from California so I've got to replace it with another California cat which is 700 dollars. I've found that a normal 49 state cat is like...

Hey all, figured that since I could not find this information anywhere else I am sure others are looking too... I live in Iowa and since we do not have any emissions crap to deal with I decided to remove the air injector system since it was in the way of where I wanted to install my OBA York...

Okay, wise and learned scholars of the AMC/Jeep world...I have taken your advice, gone to a slew of junkyards and have managed to nick maybe the only 2100 in existence in Denver for a measly 30 bucks. (It's 300 on erhemann's ebay page) and the best part? It was professionally rebuilt less than...

Hey guys, I just bought a 2001 jeep xj.100'000 miles runs great but won't pass emissions testing. It keeps giving a not ready signal to the emissions testers and it seems to autozones computers as well.. Changed the computer and same result.. Any suggestions?

Went to take the '88 Cherokee to get smogged this weekend and if failed the emissions test pretty bad. Trying to see if anyone has some ideas as to what I can fix on my own and try getting it retested. I failed specifically in HC and CO HC: @ 15mph measured 101 (ppm) - the max is 124 = passed @...

Hey Guys, I just recently purchased the GDE Eco tune. I love it. But not I've got the itch for more. What can we do the CRD to give it more power and/or better MPG and still be able to pass emissions? I've heard things like resonator, pdf, muffler? What have you guys experienced?

First, let me say I'm new as a poster, but have been a fan of JF for a long time...you guys rock and have helped so much. I gotta problem...I am trying to diagnose super high hydrocarbons in my 93 wrangler 2.5 4cyl. I've been 3 times and HC going up each time...last time at 999. I've done all...

Hello all - thank you first off for the wealth of knowledge I've picked up on this site. it has been INVALUABLE!! I'm sure this may have been covered somewheres on here so if someone could direct me to a thread or maybe answer a couple questions I'd really appreciate it. A couple months ago I...
