OK here's the story: My alternator recently died on me. It drove home just fine. The engine had the usual acceleration that it had. After changing it for a new one, my engine suddenly had absolutely no acceleration power at full throttle. So, figuring it just needed a tune up, I changed the spark plugs (which were all in HAND TIGHT!!!?!?! WTFBBQ), oil, oil+air+fuel filter, and fixed some vacuum leaks. I also unplugged the battery to reset the computer. None of this has fixed it. I also noticed, while letting it idle, that when I suddenly punch the throttle, it'll stumble and hesistate a bit, then rev (albeit a little slower than usual). I checked the throttle positioning sensor for incorrect voltage, and got ~0.9 volts idle and ~4.7 volts at max. I'm thinking that it might be the oxygen sensor, or the mass air meter. What do y'all think?
I don't know what the hell I'm talking about really... But could it be the belt? Perhaps the tension isn't right? (since the alternator was replaced) **Edit** Nevermind...we posted at the same time. Congrats
LOL, thanks for the advice. I've got one of those spring loaded tensioners which I don't think can be adjusted. Besides, the engine didn't sound right before either, so it couldn't have been that.
