Recently I put one of Norris' catch cans on the car and went back to the factory PCV. (my car was sucking big quantities of oil out of the crankcase with the racing PCV setup). One lesson there.
I also replaced all my Russell hose with hardline and Earl's hose. Another lesson there.
I also removed the stereo as I'm working on packaging A/C. A third lesson there.
Anyway, with those changes, and with no change
at all to the EFI tune, the car starts way better. 2 seconds max. It fires with a burst, then quickly drops to a fast idle, then a normal idle as the engine warms up. It's perfect.
Theories:
1. The stereo was causing a big voltage drop, causing the XFI to reset.
2. My plugs were coated in oil, and kept the engine from firing easily.
3. My car likes playing jokes on me.
4. I'm going insane.
