I'm going to throw another one out there for you to ponder on, a potential leak in your fuel line when under pressure. My friend who is balancing the TWM throttle bodies finished the front end alignment and was taking the car out earlier today and smelled fuel. Drove it on the alignment lift and found a small leak starting in the -6 braided line. Now awaiting the new -6 line to be delivered and between the two of us will get it buttoned up. Hopefully back at the house before the end of the week.

 

 

 

Fair guess, but my gauge should be solid 40 while running, which is target and I've replaced many lines since purchase. I dont think a leak is my problem. 

Certainly shouldnt affect only one cylinder.

What stymies me is the issue changing from one cylinder to another. Almost as if the coil was going bad, or the earlier mentioned dirt in the fuel line or fuel barrel leading to the injectors themselves.

 

Has the drop in exhaust temp ever occurred in more then one cylinder at a time, or always just one? The typical way one cylinder runs cold is due to a misfire, bad plug, bad wire, bad coil, but again, with this being a rolling issue makes me believe a bad coil pack vs a bad injector.
