I know a few people that use them on evo Xs an have no problem. But were not talking about evos. I went through 2 weeks of problems with my car just because of the extenders and I don't want it to happen to someone else. And I know these are capable of doing more damage then goof in most cases.
I told you they wouldn't work.

I doubt they caused you to go into limp mode, though. I'd be willing to bet that one of the primary O2 sensors wasn't properly reconnected. That would definitely cause limp mode.
