It's been good for the past year but now it died on me a couple times in the last month. So I bought all the goofy gasket rings in the intake tract (between the MAF and the throttle body) and am about to replace them. I also found a hose clamp missing so I'm replacing that, and when I was doing the starter last month I found one of the vacuum caps on the back of the manifold was cracked -- got a replacement for that too. Here's hoping it's just a minor vacuum leak and this will solve it.
