Looking for a bit of help.
My Jeep configuration is:
2010, 2 Door Jeep JK, Manual trans, 4:88 gears 35” tires, Ripp Supercharger, stage II (meaning with the intercooler) long tube headers also from Ripp and Borla cat back.
The problem I am having is that the Jeep will not pass New Hampshire state emissions. No Check engine light but the following codes:
P0171 bank 1 fuel system too lean
P0174 bank 2 fuel system too lean
In looking into the codes it appears to be saying the downstream O2 sensors are not efficient.
I don’t know exactly what this means.
I initially requested help from Ripp. They advised me to update to the newest software. This was a bit of a problem because both my version and programmer version were out of date. The Diablo guys were especially helpful with this and eventually they walked me through everything and I got the Jeep up to date and I do believe it runs a bit better than it did with my previous version. I was at 2.6, updated to 3.3.
At the time the guys at Ripp told me I needed to run it a bit before again testing the emissions which was a couple weeks ago and I have put maybe 500 miles on it since. Still will not pass. Codes will come back if I clear them. I have requested help or at least some direction from the Ripp guys but have heard nothing back. Mike at Diablo has tried to help in telling me that he thinks it is likely a leak in the intake system. I spent time looking at this today but found no problems or leaks anywhere in the intake.
I have about 39000 on the Jeep, roughly 20k of that is with the supercharger and exhaust from Ripp. I have never previously had a problem passing emissions and after some early problems the Jeep has generally run very good. Fuel milage was initially 16ish after the install but dropped to 13.5-14 by the time I got to the 2.6 tune. Mileage has never been a big concern.
In researching the codes, they pointed me to the downstream O2 sensors, the cats or an exhaust leak. I have thoroughly gone through the exhaust and intake systems for leaks…no problem found. I have checked the O2 wiring and connectors for any issues related to heat or damage from touching pipes and such. All appear to be good. The Diablo tuner allows me to look at the sensors live and they appear to be working. The cats/Y pipe have only 20kish on them so I would not think they are bad. I have asked Ripp if there is any known issue but no response from them so I’d like to know if any of you other guys with this set up have had any issues of the like?
I’d normally take it to the dealer as emissions issues are generally covered for a long time on new vehicles but this having all the add on I can’t do so without paying for hourly labor…potentially a lot…I sought guidance from Ripp and they were a bit impatient with me just with the tune and no response at all this week when writing that I still have a problem. I don’t think it has anything to do with the supercharger but I am also using their cats and tune.
I’m getting desperate here… pulled over twice today by police from 2 different towns!!
Anyone have any experience with this kind of issue? Any ideas? I just don’t know where to go next in troubleshooting it. Any advise or ideas would be greatly appreciated.
Thanks,
V
