..there are some weird problems.

By the way, for those of you who don't know, I got tboned, so I put my engine and transmission in another 240 shell.

Anyways, finished the swap today, and took it out for its first drive.

Problem 1. Power steering is weirding out. Put required fluid level in it, but it still is like on and off. Sometimes it is fine steering, and other times it is harder, and I really have to put muscle into it . I assume this might buffer out on its own? any feedback would be nice, I'd like to be able to steer normally.

Problem 2. Clutch. This is the major problem. First of all, the clutch pedal is really lose like 3/5's of the way in, and then it gets stiff, and that is where it grabs and stuff. Probably just needs bled, but some strange things happened while driving. I stalled it at a stop light and when I turned the key to start it back up, it would jerk forward, and try to drive. It did this every time I turned key to turn it on. After 3 times or so, I just manassed it and turned it on, and it crept forward, and got going. I also noticed, when I stall it, and then start it back up, and throw it in first, the clutch pedal will stay to the floor, but the car will still be driving forward. wtf. And, when I coast to a stop light, in neutral, then stop and wait. I can't put it into gear, I have to lift the clutch pedal from the floor because it is stuck, and then push it back in, and put in gear. It does some weird stuff. Any help would be nice.

Problem 3. Weird a** bass noise? Whenever I turn the car, especially from a stopped position, and take out into a turn, my car makes a bassy noise. It sounds like my subs are acting up, but I haven't determined if it is actually the subs, or my car. It sounds llike my subwoofers are making deep bass, but it isnt the song I'm listening to, and it only happens when I turn.

Problem 4. Idle Rpms. Rpms are almost at 2k at idle, even when it is hot or cold, no matter the weather. And they are always high, even after a while of driving.

Those are the only problems I noticed. I only drove for like half an hour before I realised I have some bad problems. Any help would be greatly appreciated.

Not that it matters, but just incase, the engine and transmission in the shell previously were shot, and the car had been sitting for 5 months..

A) Lift the front wheels off of the ground and turn your steering wheel lock to lock like 30 times. This helps get air out of PS systems. Also check your belt tension,sounds like a slipping belt.

B) Use a bottle to bleed your slave cylinder. The stalling sounds like your clutch wasnt disengaging, therefor it would jump when you try to start it.

C) Check your grounds and make sure they are properly placed.

D) Check your ECT sensor, and your IAC valve to see if theyre working properly. Also fiddlle with your idle screw.

And BTW, please post more specific info on the swap (motor,platform changes,etc)
