Hi new to the site and looking for info.
Have an '09 jeep wrangler with v6 gas with 90000 miles, no problems with it till the 02 sensor went out chaged the one the code reader said, check engine lite would not go out. Drove a while and rechecked said another 02 sensor was bad changed it, same thing till all four was replaced. Still no power and missing when first cranked. Took to to jeep dealer and put it on their computer, they said cat convert was bad, they told me it would take four hours to read all the codes at $95.00 a hour.
Changed convert and now have to run it out of od. Has no power when put into od. Untill it warms up about 2000 rpms is all it will rev.
Every thing is stock except the intake filter replaced it with the cold air system.
Any one else ran into this problem.
