So I installed the new camshaft position sensor and it didn't correct my main problem. Replacing that and reconnecting the injectors helped with smoothing out the shifting and overall driving experience, of course, since the whole sensing system was out of whack.

I'm left with the EZL as the remaining component. Honestly, WTF?

I wonder if the hot water that spilled out of the expansion tank and onto the vacuum line connected to the EZL caused a massive vacuum draw and damaged it.

I am irritated and would think that the EZL being bad would throw a code.
