You should post an idle log (car up to temp), and maybe one of the rpm drop to 500. Does the knocking sound speed up when you give it throttle? Is it just during start up, or while it's running?
The fuel pump is also loud, so move your head close to it, and see if it's that.
I was thinking bad injectors, until I continued reading. It seems like you've done all of the maintenence to rule those out.
What downpipe?
STFT tend to fluctuate to both extremes, and your LTFT seems reasonable at -7%. The awkward throttle response may or may not be related.
All of this RP talk interests me, since I was fucking dragged on Facebook for posting my Blackstone oil analysis, one batch of which was RP. People hate on it because it SOOOOO expensive. When, in fact, it's really not that much more than Pennzoil, Mobil 1. It's not Amsoil / Liquid Moly...
As the tuning process develops, I'll post updates. We should be onto e30 when we wrap the 93 tune. For now, here's a little compilation of how she sounds.
ETS tmic
CPE downpipe/ Triton catback
Corksport 3.5" aluminum intake
XS Power BOV
Oh, I did do a compression test, and the numbers were the same as they were 2 years ago. 155 across the board. Now, the first time I used a Pittsburgh from HF, but this time my father gave me a brand new Craftsman set. I thought the HF was just reading low because it couldn't hold 180 psi...
Next up was the injectors, which I couldn't even touch for 5 days due to my wife's and my work schedule. That was a long 5 days. I pecked away at some things with the headlamp, after I put my daughter to bed. Getting the manifold off was relatively painless. The main problem was the... yes, the...
This is where the turbo upgrade comes in. I bought a "mounted, run, but not driven" BNR S4v3 for $900. Came with everything it should have. It sat on the shelf in my "garage" for 6 months? Again, a little too pussy to open that can of worms. I kept telling myself I'd do it, but kept putting it...
Some time after, I got the JBR short shifter, rain guards for the windows, minor bullshit. Added some Enkei t6r 18x8.5 +38, wrapped in those glorious re71's (caught the same clearance as Frausty.) Like $400 shipped, but they are an odd 235/45 monster truck sized. I was able to take my 25mm...
Thought it was time to start putting some paint on this pig's face. LED tail lights, New brakes (centric blanks, EBC yellow), g2 caliper paint, Epsilon+ wing extension, Bayson r front lip, Dash Designs suede cover, Weathertech floormats, etc. Added a Progress 32mm rear sway bar, TB Performance...
I bought a Cobb downpipe, which I sat on for probably a year,because I was too pussy to get involved with exhaust work. Finally had a buddy help me—we used his quick jacks, which was awesome. The oem bolts came out with ease, and that's probably because they were taken off/on right before I...
I am currently in a standing position while writing this, due to the welts left on my rosy backside— I was publicly humiliated, admonished, and physically punished by our father, who art on Earth, JT, for not contributing to the forum, and instead watching homosexual pornography cinema (minus...
