Ok, so quick background: my cat died so I knocked it out and I've been living with the stink for several weeks. No big deal. I've installed the BHR ignition and I've got a hi-flow intake filter, so life is good after the car is warmed up. The problem has so far been the VERY rich startup mixture and vapors/ white smoke that follows me around if I don't baby the car along for the first five miles of my commutes. This is the initial richness that I suspect was the cause of the cat's demise.
Here's the thing: For the last few days as an experiment I've been sustaining the ignition switch for a hair longer than I normally would.. I mean a hair longer. I wait for the torque to reverse at the flywheel and then let off the ignition. My usual routine previously was to just kinda tweak the ignition to start the car and not think too hard about it. So with this longer ignition time.... there has been NO smoke. None... as if the mixture has been leaned-out at startup as opposed to rich. It's awesome... but I have no idea why the car is doing this.
Can anyone comment on this? ECU protocol? What?
Thanks
