audi-tude

So I received alot of advice and alot of constructive criticism about possible problems, resovior sensor, heads, water pump, etc... but the one thing I never thought about was the simplest problem, the resovior cap was missing a small piece of plastic by the edge of the threads so was leaking air into the system. So I guess, live and learn. cost me 80.00 for the shop to figure out what it was and to fix it, well, buy a new one and screw it in.
