So since the price diverged from #2 by 20 cents or so, I have used 2 tanks of regular diesel. My rock and roll at idle has essentially disappeared. It started when I first started using HPR now that I think about it...hopefully after I reseal the delivery valves, I'll have no rock and roll with HPR.

The car feels much more peppy on #2 as well. hmmm...

It sounds like I have knock on one cylinder, which fades away to nothing after everything is good and hot (20 min on the freeway). If delivery valves don't solve it, I'll look into the next step. I can't remember which injector had the same heat shield used on two installs, though...
Old thread so this may already be fixed, but heat shields CANNOT* be re-used.

(* They may be re-used if you bend them back to the original shape, but there is a risk that they won't seal or last as long as a new shield. A failed heat shield will probably result in the injector heating up too much and fuel burning / solidifying in the tip of the injector and ruining the spray pattern, resulting in smoking and rough running and poor performance, and ultimately you may have damage to the injectors, the pre-chamber, and to the piston / head, and that gets really expensive.)

See here for a nice couple of pix and more info:

Do I NEED new injector heat shields?

Filled up at the Union 76 near my house this morning and found the pumps said 99% bio-diesel. Might be the same as Propel's HPR, since others in this post reported finding that at a Union 76. In Sacramento, those are mostly at Shell stations. Price was $3.89/gal vs $3.85/gal for Propel last Sat (my other car). Price is between regular and mid-grade gasoline, which is currently pricey in CA due to refinery switch-overs. Couldn't find anything about in a google search.
