yeah, in most cases I probably would have taken it to pepboys just to see what they said or just gone with a NAPA cal cat which has passed it the last two times. But being that I just paid for a new cat (I got a discount at Kragen, even though I swore last time I was only using NAPA), I didn't want to rebuy a part.
With regards to the sensors, well, it was all planned to do eventually....I figured I wanted all new sensors in a new engine....hell, wanted to do the Hesco wiring kit too, just didn't have the funds at the time. (old engine had an engine fire and many of the old sensors continued to work but had suffered some damage)
I also kinda figured a lot of the 50 state mods might be fine alone, but when you start popping them all together (injectors, air filter, header, cat back, hi flow cat, etc.), they have to have some sort of chain reaction....one of the reasons I generally stay away from hi-flow cats....but I thought with a brand new rebuilt engine, I was gonna be safe.
As for the injectors, yes, they were reconditioned, but they came with flow specs from Precision Auto Injectors, and they were all dead on. I have wondered if the multi-port injector vs. the single port injector that comes stock might also have something to do with it, generating a finer mist and consequentially a more efficient and hotter explosion.
And yes, the new engine did get new freeze plugs, but I saw the engine while it was being build, and happen to admire the new freeze plugs as I had rusted a few of my old ones out and it was a concern....they all looked to be completely flush, so I don't think coolant interference/restriction is an issue.
Sealing up the exhaust hole made a huge difference....and I'm curious if I need to run some seafoam through the intake to find any other potential leaks. I did check the torque on the exhaust/intake manifold and it was dead on.
Don't think I mentioned, either, I checked my oil, which is only about 1500 miles, but maybe 3-4 months old, and it was black as coal....it was also about a 1/2 quart too full. Freaked me out at first, I saw bubbles and thought a head gasket blew, until I realized it was just air bubbles. But hoping a new oil change with correct level and a new filter will help stabilize it too.
And I wish I could pull, or short the temp sensor, but that's gonna throw a CEL, I tried, and that in itself will fail the visual test. =(
