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.

1996 Saturn SC2 Owner Comments

problem #1

If the car is in 5th gear at a low speed, say 30 mph, the engine makes a rough rumbling noise, almost as if there is a fuel delivery problem or the pistons are missing.

After replacing the spark plugs, the car ran much better for about a day. Then the low rumbling noise came back the same as before.

The next day, the low rumbling noise was worse than before ever changing the spark plugs in the first place.

I am now thinking that I will give each spark plug one last little tug just to make sure they are all on tight enough. (Although they are probably just fine.) Also I certainly will not put too much force into retightening them for fear of messing something up. Then after that I might replace the fuel filter, since I have heard this is not too hard and fuel filters can cause problems and hey why not replace the thing anyway.

What does everybody think? My next step is to look for an automechanics newsgroup, though such a thing probably does not exist!!!

Thanks for the help!
