Question about 2002 Pontiac Firebird
When I am accelerating, driving awhile, or turning, my car makes a grinding sound. It is not constant, but it is more noticeable when the car has been on the road awhile like a road trip. I had the catalytic converter changed and had the rear assembly changed. A few years ago, the transmission was rebuilt-2007 maybe. What else can be causing this and what do I need to check or do to solve it? =)
Sounds like a wheel bearing. Jack up front end and spin wheels by hand and listen for grind. Same for rear wheels. Make sure brake linings are good all around. Do the swerve test. Drive down road bout 40mph and swerve moderately one side to other. If noise gets louder with weight shifted to one side more than other its most likely a wheel bearing.

This problem is caused by the headlight gear being stripped. If you go on ebay, there is someone who sells brass headlight gears. Once you put the gear in, you will not have this problem again. . . unless the other gear goes bad. It's usually the driver's side headlight that does it.

Most GM it takes about 100 start cycle to clear any DTC codes that do not reoccur. As for the lack of power when accelerating could be a dirty fuel filter and needs to be changed.
As for the EGR Valve code it may be getting carboned up and need to be replaced or cleaned soon with carb cleaner. First try changing the fuel filter for your lack of power.
If you are ever going to have you Montana Rescanned and don't mind spending a few extra dollars, Have a Dirve Cycle DTC test done. http://myweb.accessus.net/~090/dtcobd2n.html
Good luck and hope this helps. Note: The program on the transmission on the Montana thanks to GM and there wisdom was made to slip when the transmission is cold to warm up the drivetrain quicker, which premature failure is common around 150,000 KM or 100,000 Miles just after the warranty. Regular transmission fluid and filter change will help exten the life of the transmission on the Montana.

Check your alternator see if you have a drop in voltage on your tack,then it is the problem.I too was a victim of high price tune up and still had a problem with a misfire.and cover your coil pack with a piece of rubber water run of onto your power pack .Another thing is to use a silicone spray on all wires.

The forward clutches are going bad is the most likely problem. To repair the trans should be rebuilt.

Testimonial: "That's what I was afraid of, a total rebuild. "
If you have a warranty from your dealer, you paid for it, or whether it came with it, it doesn't matter, you MAKE them honor it. Take it back there, and MAKE THEM FIX IT! This shouldn't be your problem if you have a warranty. If they aren't honoring it, threaten them with the BBB or court. They will shape up.
I would say power steering pump.First check to make sure there is fluid in the reserve tank and at the proper level if not top it off and whine should stop.If level is correct then maybe try flushing with fresh fluid.
3.8L engine the power steering fluid was never toped/checked.. because it is a pain in the *** to get at (behind the hot as hell alternator), so it probably ran dry, top it up is probably all you have to do.. if the whining presists then you will have to try and bleed the air out by jacking it up, engine off, turn the wheel one side to the other about 25 times.. if that dont quiet it up then you will have to replace the power steering pump.
Power steering pump / fluid level is not hard to check - it is located below the alternator on the passenger side of the engine bay. You need a light to see it. You can get your hand down from the top of the engine to loosen and remove the cap/dipstick.
