Need Help QUICK Please! BIG Problem.

My car has been running okay for a while. Then the belt starts to squeek when I idle...Sometimes for a couple of seconds, somtimes up to a min...Either way, it doesn't run all that well while it's squeeking. It feels like theres a bog but after its gone, the car runs fine and maybe occasionaly squeeling here and there. Nothing big though. Anyways, this weekend I was gone out of town and I left my car in the garage...We left Friday night, came back Sunday night. So about 2-3 days without starting it at all. When I came back, I started it, and it was perfect. I came to a light and I hear the squeeling again. I run it hard hoping that it goes away but it comes back. Anyways, from that point on, EVERYTHING is dim. The lights inside/outside are dim. Interior lights, headlights...EVERYTHING. I'm guessing it's cause I didn't drive it for such a long time and the batter just needs to regenerate itself....The weird thing is while its squeeking, the car idles hella low like it's gonna die or something. I try to drive fast and somewhat hard so that maybe the idle would come back up, but it stalls out when I let go of the gas and clutch it. I start it again, and everything is still dim. The headlights pop up really really slow and just about everything you can think of that's powred, was 10 times more weak. Anyways, I floor it again, in gear one, and it feels fine UNTIL 3500-4000 rpms. The rpms just stay there and the car seems to NOT MOVE and BOG. I'm not sure what's happening and I dont' have an A/F gauge but I'm looking at my boost gauge and its just as the motor was running fine until those RPM's where it just stays there and nothing happens....I feel it bogging if I keep down the gas but the car doesnt speed up, nor does the engine rev any higher. Can anyone tell me what's wrong? Thanks..BTW, when i got home, my hKS turbo timer went kooo kooo too. I turned off the key, adn the car shut off withouth counting down. after the car shut off, the TT was LIT but no LCD. and the ignition was in the ACC position withouth the key being in there so I'm thinking the turbo timer has something to do with it as well...I hope someone can help me..ThankS

Bad Alternator?

but why wont the RPM's go above 4k?

ya..i was gonna say it was possibly your alternator, but then the rpms came into the picture. i've never heard of something like that happening. i dunno if this could be similar, but i have had a bad ground before in my car (a bolt on my alternator was touching metal) and it was causing things to dim, plus it was also causing my car to sputter. mine never just bogged down. im not saying that is ur problem...but just keep it in mind. lata.~Scott
