My car does the same thing, I have spent about $500 in parts trying to figure out what it may be. If you get it figured out please post the answer :-)

I have a 2005 Buick LeSabre, it ran hot one morning and i heard this clicking noise coming from the engine like the valves were'nt getting oil or something. Now when a crank it the engine runs like it has a bad plug or two and there is constant bubbling into the water reservoir while it's running. I have been told that it's a blown head gasket and am asking around too see if that's what it is or could it be something else, the constant bubbling in the water reservoir is what has got me? but anyone that could give me some suggestions on what it is would be much appreciated. 4 Answers

Changed Maf senor, crankshaft, fuses, spark plugs. fuel filter and ignition modulator and the car starts but only runs about five mins. before stalling. No engine light comes on. No bad codes show up. Can't find any bad hoses. My mechanic teacher has looked and we can't figure it out. I am a student and can't afford to fix much more and nothing I have spent money on has worked so far. When I first put the maf in the car worked great for about a week but the transmission was still skipping 2 Answers
