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.

CarComplaints.com Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

Looks like others have seen this too, TSB #00156A -- 4.2L LL8 ENGINE ROUGH IDLE - RUN POSSIBLE P1345 OR P0016. *MJ *TT (NHTSA ID #10007656, JANUARY 01 2004) . So far two auto mechanics don't have a clue how to fix my vehicle. Replacing the cam/crank sensor didn't fix, running the procedure with the computer installed to go between 5-6k RPG with the brake applied didn't help.
