OK. So I replaced the 4-pin coolant temp sensor and it seems to run a bit better yet.... Lambda reading is still weird though. Now, it fluctuates, but only by .5v. It's still reading 9.2V at idle. When you open throttle quickly it jumps to 7v, and then back to 9.2v at idle. If you stop the engine and restart...the idle reading is 7v again! Then as soon as you rev, it and let it drop back down to idle...it's back to 9.2V.
Don't really want to mess with AFR adjusting until I'm sure there are no broken parts that would skew the reading. What next....?
