Suddenly super lean while at cruise

[scheides]

Thx for the advice! The water in the strut tower was b/c this pic was taken just before the all mitsu cookout, and I was doing a bit of cleaning under the hood (long before this all happened). The plug wires are almost brand new, 10mm taylors from elite. The #1 (shortest) plug wire actually had a minor manufacturing defect which I noticed after this was happening. The metal part that sticks into the coil for contact was only about half-way in (that's as far as it could go), and the tip of it was covered in carbon build-up. I adjusted the boot and it fits well now, but I did not clean off all of the carbon, as there was plenty of clean contact space left.

I swapped out to the original coils I had in the car w/ no change a few days ago.

I'll swap out the plug wire(s) & see if it helps.

btw, plug wells are dry.
