Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 Jeep Wrangler Owner Comments

problem #1

Jan 312008

Wrangler Rubicon 4.0L Straight 6

  • Manual transmission
  • 34,000 miles

My Jeep Wrangler Rubicon idles well when first started but as it warms up it begins to idle roughly and the idle drops a couple hundred RPM. It seems to be using too much fuel but it is hard to say as I run larger than stock tires. Lately it has been producing the occasional skip or hesitation when under load. The problem is slowly worsening. I have played with the idle air controller and cleaning it seems to help for a few minutes but the problem always returns. I replaced the idle air controller but it made no difference. The water temp sensor was replaced as well and also made no difference. I do have a snorkel on the Jeep but it runs the same when I remove the plastic air intake directly from the throttle body. ANY IDEAS?
