For about 3 days now, my car has been making an odd noise. It almost sounds like the whine of a dieing power steering pump, but it only seems to make this noise in closed loop! I know of no way to get it out of closed loop other than shutting the thing off, so thats what I am basing this on. Warm the car up, take it out for a drive, noise starts up. Inside the car is sounds like excessive blowing, or maybe like a really loud vac leak. Outside the car is where it remonds me of a power steering whine. The only other real symtom that something might be amiss is that it seems to take a while to get into reverse (its an auto), but again, only at closed loop. Shut the car off, turn it right back on, you'd think you had a pretty good running Trans Am! Any ideas on this goblin? If it is somehow the trans I will hold of doing anything until I can afford a t-56

Start looking at the AIR pump and diverter valve. I'm guessing you have a valving issue.

maybe a tranny pump??

Thanks for confirming my suspicion Vader....I really didnt want to do much with it until I had a real clue on what I should be looking for. I honestly dont know why, but I just have a real bad feeling about that tranny, I guess I just don't trust Auto's....no matter how hard I argue for them...I think I'll go check that out now

Yeah, sounds to me like the AIR line that goes down to the cat is unplugged somewhere before the check valve... when it's in open loop all the AIR output goes into the manifolds, when it goes to open loop if gets sent to the cat. Check that run of tubing, from the air mgmt valve in the pic down to the cat.

i agree also.

right now i don' have my air tube going to my cat hooked up to anything. so it makes that winning sound. its really anoying. i need to do something about it all...

I remember when my car had that stupid little black box on it. OoO the memories

Well, my fears turned out to be correct.....I didnt check it right then cause my apartment management was out, so I decided to wait until last Sunday.....Well, believing it to be a realitivly harmless exhaust problem, I took the car out saturday for some lunch. I had to stop at the bank, so the car got good and warm going to wendys. After leaving the ban the noise got louder, and began to sound like grinding metal. After getting my food, I pull out to make a right turn on to University Rd in Denton. Traffic is annoying, so after sitting for 7 mins or so, I decide next break in the right lane, I'll just punch it and go, deal with getting into the left lane after....So I punch it, I move a little, and then the motor revs waaaaaaaay up, I figure I just hit it too hard and spun the tires...the guy now right behind me is very annoyed, so I try and hit it hard, but not as hard.....it just revs again. I slowly get on it, I hear a high pitched whine, go up in pitch until about 2000 rpm, and then go down in pitch and then go away around 4500 rpm...barely on the gas, at 4500 rpm....Its stuck in 1st gear! So I just pray it doesn't die on the way back, so I get back (about 2.5 miles) going about 30 or 25 MPH at 4500 RPM.....very embarassing...So hopefully I'll be able to get a t-56 in there soon
