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.

For the past month or so my 2001 Pontiac Grand Am SE 2.4L, V4, began to lose RPMs while idling (usually dropping from '7' to '5-6') before jumping back up to the normal idle rate. The real issue however would come when making a turn while also pushing down on the brake, when I would lose all power at times, including power steering and brakes. Luckily, this only happened to me on residential streets with no traffic so I was able to coast to a stop and throw the car into park and then turn it off. After turning the car off, I would able to restart it right away with no issues and go on my way.

After reading some reviews/possible fixes I went ahead and took off the intake manifold and changed the IAC valve and cleaned the throttle body valve. I also poured in a fuel system cleaner just for good measure. After buying the new IAC valve, throttle cleaner, and fuel system cleaner, it came out to be around $100 for parts and with the driving around to get the parts, to be about 3-4 hours of work under the hood (did the repairs with my Dad in the garage). I've been driving around since we did the repairs and the rough idling seems to have been fixed and I have not lost power while decelerating (and I've been running it really trying to get it to repeat the power failure/rough idle). I'll update if anything changes, but it looks like this did the trick!

Update from May 26, 2016: After a few days, I lost power again while turning in a residential area and again shortly after on a heavy traffic stretch of road (stop and go). I finally caved in and took it into the shop. The reason for the losing power was a bad hose going into the intake manifold that was not sending the right amount of air, causing the engine to stall out. It's been about 3 weeks now since the hose was replaced and I have not lost power since. Every now and again I will have a rumble while idling, but it's not nearly as severe as it was previously.

After I finally saved up the money to fix the leaking coolant/cracked intake manifold problem, the car started shaking oddly when shifting gears/idling. It's been sitting in my driveway ever since. I hate you, GM.

After running back and forth with the kids, stopping at a light or sign, the car will start vibrating. Giving it some gas it smooths out but once you let off the pedal its back to shaking it baby.

Well lets see, it would be a very short list of the things that still work correctly in this dried out turd, but lets skip that and head straight to one of its many problems. I've had the fuel filter replaced, nothing. I've had the air filter replaced, nothing. I've had a pro clean out the fuel injectors, it worked for about a week. I've replaced all the plugs and wires, NOTHING. I've given up on this car, and want a new one , but I can't really sell it or trade it in. Plus I still owe about 3000 for it. And now the trans. is going out and i'ts only at 98000 miles! I must thank Underriner Motors of Billings Montana for making me such a great deal on this p.o.s. car.

As a single mom and having to drive my son to and from school and then drive myself to and from work plus go to evening school, I thought I had purchased a car that did not need too much TLC, but it has only been three months and this annoying noise is just not looking good, can't afford to be without a car. The annoying jerking, vibration does not happen when the car is moving only when I stop at a light or stop sign, it's like it is going to die on me.
