That's what I figured. I did that, maybe not for that long or that fast, but my exhast is quieting down a lot. There are still three problems though. The first is that I'm almost positive my VTEC isn't kicking in. I can always hear/feel it and it's just not there... the second is that it's been idling rough ever since. Nothing bad at all, but I can feel and hear the difference. Anything I can do about that? Finally, the last problem is the rev limiter/fuel cut-off. I thought these were electronic and factory set, and not changable by the ECU. Every since I took the lude swimming though, my revs are capped at about 300-400rpm before redline. I always used to be able to take it a bit OVER redline before the fuel/rev cutoff kicked in. What's that all about??? Also something I should probably say is that I've had my CEL on for a bad EGR valve. It's on special order and on its way, but I'm not sure how that valve might affect everything else...
