My 1998 Pontiac Trans Sport 3.4L is idling a bit high. Current idle speed is about 1150rpm. I get an Idle Air Control code. Changed out the IAC but still idles at about 1150.

Are there other sensors that can affect Idle speed?

I'm looking at parts at http://genuineaudiparts.com/parts/1998/Audi/A4 Quattro/index.cfm?action=partDetail&section=BODY HARDWARE&group=ROOF&subgroup=SUNROOF&component=Drain hose&partnumber=3B5877233&vehicleid=182717&siteid=214407 part id: "3B5877233" (rear)
The Diagram makes it look like a really short hose which I think is just the site cramming all parts into a small diagram. So is this the right hose for fixing the water leak in my '98 Audi A4 Qauttro's moonroof? Also since I'm bothering with replacing the hose should I go ahead and buy new drain valves in the rear as well?

My iphone 4 gets EXTREAMLY hot when charging, to the point it burns my hand It also will not hold charge even when I plug it in. Any help?

How much to build an engine?

Okay so I can buy a 1980 camaro shell for 700 but its just the shell no interior nothing so I was wondering if I have 15 grand what can I do how much would it cost to build an engine around 300hp I dont care about the engine being original or stock and what would it cost to get just basic interior for the meantime to drive it? paintjob i dont care that will come later im more worried about engine and interior

So you have two warning lights on and you're either ignoring or resetting them and your question is, "Should I be worried?"

Yeah. Since you just cleared the trouble codes, drive the vehicle until it comes back on. Then get the trouble codes read and find out what's going on.

Did you think the engineers installed those lights just to mess with your head?
