Various problems! help!
ok.. Got the car back together totally today. Got some problems.
1: I got it to idle (BAC had no wire! oops! ) but it seems to idle at about 2500RPM, all the time. Maybe this is just the warm up, but it should have settled once it got warm. Then again, maybe not, because
2: The car was hot when I shut it down. This is because I just took it for a spin with no fan (short drive), it did NOT overheat), but the water temp gauge just stayed all the way at the C the whole time. do these sensors often die? or could it be the wire, or what? If I fix this, will the idle settle down a little lower than 2500? How do I fix this?
3: I noticed a slight misfire/stumble. All the time. I dunno about WOT/above 3800, because I was pretty gentle. AUGH! BUT my oxygen sensor wasn't hooked up! Could this be the problem? WHERE THE HELL DOES THE CONNECTOR GO because I couldn't find it The plugs are new, but the wires are not. Could that be another part of the problem?
4: Oil pressure. my friend said there was zero oil pressure when I first started it, and that may be true.. I forgot to check the gauge. He said it shot up INSTANTLY after I drove for about 20 seconds. All the way up to the peg, which is where it was when I checked it. At idle, the gauge is pegged. Is this a problem?
5: umm.. that's it. There is no 5. if there is, I forget what it is.
6: I lied! Just remembered what 5 is. Now it's 6. I can't get the bolt nearest the engine on the turbo-precat tight. I can't see how the hell to get a tool in there. How do I do this? ahhh!
7: One more! wowie! My heater fan doesn't work. It worked before I pulled the engine. Any ideas why? could anything have come loose in the engine bay that would affect this?
Thanks for all your help, I REALLY appreciate it!
everyone, thanks for your help!

too bad nobody around here has a turbo... unless I go to london or something
I think my driveability problems are due to lack of O2 sensor, but what about the rest? Some of the idle might have been due to a vacuum leak, too (one vac. hose disconnected, went to the pressure sensor).
Oil pressure is probably a dead sensor, good thing I have a spare one on the old motor that works!
How about the water temp though? That should still work, and I don't know why it won't!

You obvioiusly dont have 110psi of oil pressure, nor do you have 0 (or the car wouldnt be running anymore) so it is a bad electrical signal.

ok, cool! I found a vacuum leak yesterday, and fixed it (after the drive!)
at first I thought I had no boost, but then I found the pressure sensor line off...
good, maybe that fixed it. Once I get all these issues settled and all the things on the car, I'm going for a long cruise tonight.

one more question... It's an s5 motor with an s4 ecu.. s4 externals too.. stock boost levels, premium gas required? What octane? 91 is prevelant around here, is that good enough? The only place I can find 94 is at sunoco, and the nearest one is like 15 miles away, I don't want to go on a 30 mile trip just to get gas.
