Yeah definitely sounds like a blown headgasket (most likely) or even a cracked head or block... Do you have a compression tester? It would be good to see what your compression looks like...

Some checks to see if your car is burning the coolant:
-Is the exhaust white?
-Does the exhaust have a sweet smell?
-Let the car sit overnight and have someone else start it while you watch the engine. If you notice it stumble when it first starts up you are definitely burning coolant, the coolant in that cylinder caused it to misfire and stumble...

Yeah if you can notice the engine stumbling when it first starts up after sitting overnight... It will go away almost immediately usually.

I took it in yesterday and we found a couple of sensors off. One temperture sensor and cylinder #6 was out. I replaced all the plugs with motorcraft plugs and that cylinder and sensor man the car runs great again. No ticks or anything. The prevoius time the mechanic had put some Autolie spark plugs maybe that was a problem. Can it be?

If you were losing coolant you definitely have some kind of problem that has nothing to do with spark plugs or sensors..

What's this about no ticks? So it was ticking before??

Yea like it had a misfire and then replacing that stuff sounds quiet starts on the dime and boost kicks hard. The car feels like the first time I bought it.
