Please take a little more time in the composition of your posts. It makes it a lot easier for us to accurately help and makes it less of a chore for us as well.

As for the battery, are you saying that it keeps ending up drained? If so, even if the original problem wasn't simply a bad battery, the battery is probably shot now. Check for parasitic losses when you've got a fully charged battery connected. Shouldn't be more than a few hundred milliamps of draw.

The most common replacement for the stock blow off valve for a car that's stock is a certain model Bosch bypass valve (aka blow off valve). I don't know the model myself, but you should be able to locate the specifics easily enough by searching "Bosch BOV" on most of the Supra sites.

With the power steering the problem could be any number of things. A bad power steering rack, and clogged line, a shot power steering pump, emulsified power steering fluid, or even a bad belt. For more info on trouble shooting the power steering system look here: MK3 TSRM On-Line

Ok here's the update, i took my car to a speed shop to get my car checked out and fixed and he found a couple of problems, one the spark plugs had oil on them due to a lack of a valve cover gasket so he had to clean it up and reseal my valve cover, and the the timing was WAY! off cause the car probably ran so bad because of the half ass build up he the former owner had to set the time off just to run the car so he set the timing back, the wiring harness is screwed up he patched it up but he suggest i get a new one. Now i need to know where can I find a place to buy a wiring harness???? beside a junk yard

Other than Toyota, I'm not sure... But that'll be a pricey purchase there. You could look on eBay, they surface on there from time to time, but they typically will be missing a few connectors so you'd probably end up donating pieces from your current one to the "new" one you get from eBay. Other than that check the Parts Wanted/Parts for Sale part of the forum. If you have no luck anywhere, than I think you'd have to hit up the junkyard. But I'm sure someone else will chime in here that has another great place to pick one up...

My waste gate is stuck open...anyone know where the heck i can get one???!!!

The wastegate or the actuator? The difference is very important.

I see you're local, I may be able to offer you a hand and I *might* have a wastegate around here somewhere.

Oh, I'm in Denver, BTW.
