CA SMOG failed Again -rant - considering salvage

Hello Jeepers, long story here….
My Jeep has failed the SMOG for the 3rd straight year; it has failed smog since 2008. 2008 failed(174K miles), spent $1265, don’t ask me what happned there, the smog repair center kept replacing one component after the other (O2, EGR, CAT) and test(and charge me)….I took them to BBB and “nothing happed”( no, quilt literally nothing happened). Well, 2010 failed again (186K miles), a little tinkering with the idle screws and it passed.

Fast forward to 2012, it failed again:facepalm:, this time HC and CO was high. The shop that told me that was going to adjust carb ended up “tuning” and changing O2 sensor. Retest, HC and CO passed, but the NOx failed this time around which was fine before ( measured 12xx when max allowed is 600 something, I can give the exact number as soon as I get home)….there goes another $200 some odd again. Unlike last few years, this time, I have a wife and a new born, so fixing this is no longer a priority at home, especially since this Jeep keeps needing repairs all the time( seriously, there is always something that it needs every month) . My wife has asked to just get rid of it (plain and simple- we cannot sell it in CA as it is NOT SMOG legal anymore).
For the first time I have to agree with her. I cannot spend any more money on this Jeep. It just does not cut it.

I agree that it has 195K miles but here is a brief history. Bought is 2007 with rebuilt engine at 167K miles(engine still runs and sounds fantastic), over last few years, I have changed, starter, alternator, carb, water pump, belts, cat( twice), entire brakes system, radiator, clutch, interior including carpets, seats, I painted the entire Jeep, got hardtop, full doors, off road tires, u-joints etc. The list is endless.
I also agree this Jeep is in its twilight but what bothers me the most is that the engine sounds and run great (no kidding). I have always taken care of it properly and never abused it.


In a nut shell, the issue lies within the carb, it is and has always been the carb. I just know that…It runs fine is SFO bay area(almost sea level) and when I haul it to Tahoe( 6K feet and up), it totally acts up. Again, take a screw driver and tinker with the two screws on the carb and all is well for some time. Come home, it runs rich…back to screwdriver again.
There is one mechanic that I trust (and don’t at the same time) but usually take his advice. I have asked him if there is any way to tell when the carb is set correctly (atleast to pass the smog). He says, bring to the shop and he will “try to fix” the carb and tell what needs to be done. A total of 2 hours at $120 something an hour! Well, that is the whole point; I cannot spend another 200 something just to listen to the same old story that I need to take it to the smog repair center to “legally” replace this and that.
When the Jeep came back from the SMOG repair center in 2008 the idle was pretty high, I say about 850-900 something( normal should be 730 max). I have a feeling that all the things they replaced were just a scam (atleast half of it)…all it needed was a good card adjustment and a quick tune up.


Now, I’m done with all the whining and rant. Sorry to put you guys to through this but I cannot count on any local mechanic that I can trust or pay extended services. I cannot even pay up the Non OP and keep the Jeep as I live in an apartment complex (no unregistered or expired sticker on the lot).
The only question I have now is: how to adjust the carb and know that is upto factory spec? Why my carb does have two adjustments that seem to do the same thing? (Note: Ignoring the one that is towards the passenger side, it is the cold start idle). Of the left most two screws that seems to control the running idle and traffic stop idle (or whatever they call it), both seems to push the same unit on the carb, well, at different points. If it is Air versus Gas, can someone tell me which of these two screws controls the Gas, (high NOx means low Gas- running lean, right?)
One other option that I got was to replace the carb with EFI but that’s $1800 for just the part....

Let me know guys...:popcorn::popcorn::popcorn:

I find it unholy to salvage a Jeep- period, but with the blessing of YJ owners…

Some pictures of my Jeep to keep you guys entertained:

I'm not going to pour salt into an open wound about your "repair story." Why salvage it, just sell it out of state, done.

I'm open for that...and with no rust anywhere, it might be doable.

Yeah I think so, or get a non-CA relative to buy it from you. I just flew out to VA from NY just to buy a jeep and visit relatives, and drove it home. Seems like a waste to salvage a running jeep that you obviously have sentiment regarding.

Man that sucks....the more and more I read, I'm glad I dont have to live out there. That being said, why dont you change the carb to something other than a stock one. I wonder if there is anyone passing with a motorcraft or weber on theirs? They are light years easier to tune than that old jeep one. Another thing is that your ECM might be acting up and not calibrating the carb right (most mechanics I know have no idea that the early carbed YJ's have ecms too) The other thing I read is that you said they set the idle high the one time you got it back....this leads me to believe it disperses less smog at a higher RPM than at your 730ish setting.

Exactly what the smog repair center had done in 2008( at least that is what I believe), after all things failed...They just masked their inability to fix the carb by high reving and skewing the results.

Webers aren't legal in CA for vehicles that need smogged. Besides the OEM Carter, I believe the Motorcraft and one other are the only legal ones. Over on the jeepforum.com site, there are a couple of CA guys who are quite knowledgable about carbs, maybe you should try posting over there before you give up.

if your willing to spend some money it can be fixed and not be a problem again. install the howel fuel injection, the kit costs about 1200.00. be sure to get the CA. legal kit.

I feel for your situation. I have friends in CA who are trying to smog-pass a classic Triumph they just restored. No amount of anything they do gets them passed.

Thanks, I know $1200 is not lot of money in retrospective (considering buying another vehicle and all) but my wife is pretty adamant about not putting in more into this… and I concur( BTW, I was quoted $1800, may be different brand). I did some calculation and I feel I can get another 20K Miles out of it before the engine totally dies on me. That could mean a Jeep for another 4-5 years at the rate I put in miles on it. I need to rethink...:confused:

I'm little apprehensive about putting it on craigslist...I do not want the new owner to go through what I know is coming his way, unless he is a smog-repair mechanic(he deserve it).:hide:

you said your at about 200k right?
i would say you have at least another 50k out of that engine, more if you put that little mileage on it every year

What do you want for it as it sits? I would buy, fix and run it (Im also a Cali smog tech).

Where are you located? Would you consider a partial trade?
I have a 97 K1500 Z71 im selling...

I'm in Santa Clara, CA! I will pass on trade unless it's Pete 387 with CAT 15 and 18 Speed (500K to 700 K miles) AND RED. :dance:

Ahem...

ALSO: the little screw you want to turn to change the mixture only affects the mixture at IDLE, and we run our smogs on a dyno, off idle at 15 and 25MPH, under load.


Your best bet, if you were to keep it would be to install the Howell TBI kit and be done with it forever.

I am interested in buying it, but remember, without a smog, its not going to sell for much in Cali, and I would need to fix it , so....
