Well, my EGR problem persists, kind of. I get a CEL when the car first warms up, then it goes out. Depending on how it happens to feel at the moment, I may or may not get a CEL when driving. It doesn’t seem to follow any pattern; it will come on, then after 30 seconds or so it goes out. Sometimes it stays on. I plan on doing an H/C/I later this year, so I’ll have another run at it then. I did put on my CAI. It doesn’t really do anything with the car being stock, but I figured “Why not?” Turned out to be a total PIA, even worse than the stock unit. It looks like the angle coming into the MAF is a bit off, probably because it’s made to fit a car with an aftermarket induction system. I finally got everything lined up and tightened down.
