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.

I'm just not sure, but I think it may be in the cold start or throttle sensor. Any one have an answer?

It seems OK after the car is run for 15 to 30 seconds if I step on the gas and bring the RPMs up to about 12 to 15 hundred and then take my foot off the throttle and let it idle. The service engine light came on for about a week, then went away all by itself. But I still have this rough idle at start up some times. Thanks Chuck F
