So I think I know what the problem is now. I decided to inspect the camshaft sensor and the crankshaft sensor today, and saw that one of the bolts on the camshaft sensor was loose, even though I had torqued both of the bolts to spec after I replaced the synchronizer. So I thought I'd unscrew the other camshaft sensor bolt to make sure the sensor is seated correctly and bolts down uniformly. While trying to unscrew that bolt, my camshaft synchronizer began to turn--apparently the bolt that holds the synchronizer down (which I had also torqued to spec) was also loose. So I'm guessing that the synchronizer slightly rotated while driving, causing my timing to be off.

So I think that all I have to do now is set the #1 piston to TDC compression and then use the camshaft synchronizer alignment tool to get the tab in the synchronizer to correspond to TDC compression, and then bolt everything down more snugly.

My problem now is finding TDC. As mentioned before, I originally found TDC by lining up the "0" degree mark on the harmonic balancer with the triangle/wedge located to the right of the crankshaft sensor, and then I verified it was correct by using the alignment tool on the camshaft synchronizer. The triangle/wedge, however, doesn't come to a point, but instead has a flat end that spans maybe 2 to 3 degrees on the harmonic balancer. It wasn't an issue originally since I could use the alignment tool on the synchronizer to verify TDC, but now that my synchronizer has rotated out of position, I can't do that anymore. Does anyone know exactly where the 0 degree mark should be on the flat portion of the triangle/wedge? I think I remember it not being in the center, but I can't remember which edge it should be aligned with (or maybe it was in the center?).

Thanks again.
