It got new plugs and wires three days ago, The old ones had this light brown coating all over them and were gapped too wide. New AC-Delco plugs @ 0.60 installed.

The Fuel pressure went from 38 at idle to 42 when i removed the vacuum line from it.

The latest scan is uploaded www.damemorder.com/scan/

I was thinking that too... But the MAF'* aren't what I can get with it sitting still, The headlight must be in the way, I need a CAI box and ram air....

That coolant leak came back again. Can I pull my UIM and tap and plug the holes in the LIM like the SC cars do?

probably not, due to the plastic UIM.

take your time and get that UIM fixed first. No need getting coolant in your oil becuase you rushed it.

Would your friend mind getting the new TB on his car?

Secondary thoughts:

On this run the IAT was picking up really hot air, which should negatively affect the MAF reading (hence power) BUT the reading this time was actually ~800gr/sec HIGHER at its peak reading.

Averaging out your spark advance at WOT your old reading was 20.2 while this one was 21.7, and much smoother and consistent. Could just be the pump is acting right for a second though...

Your coolant temp was considerably colder also...

Yeah, Trav is at work... That and He'* not into R&D at all, he just got the car

My UIM only lost a little peice, Making it leak coolant... if there was no coolant there to leak, Problem solved. And I mean tapping a plugging the holes on the LIM side, it'* solid aluminum.

The weird part is that the car idled 28 minutes longer on the second run, It just won't heat up. Of course it won't hold coolant either...

Hmm...the little bit before the WOT run shows a bit of a rich condition, but I doubt so much that its running colder. It ran for ~30min and still didn't warm up? hrm
