Sorry to hijack but My SR has almost the same issues and runs richer than it should (10.0 at WOT) and is running an enthalpy tuned ecu could it be the knock sensor as well? The temp gauge recently started reading all over the place as well so could it be a coolant temp sensor? Or both?

Haven't had a chance to do much yet but I did take a picture of the knock sensor. Doesn't have any cracks or chips on it anywhere.

Went and got a pressure tester and checked the fuel pressure, seems to be good. It read the same with the mafs plugged in and with it unplugged, not that it should change. Can't really get to the fpr to check it with the vacuum line unplugged but I don't think that's necessary. The pressure does raise in relation to the throttle position and rpm's.

I've never had a Ka but I've pulled a lot out. There is a tube that gos to the egr or some emissions bs that ties into the exhaust manifold. If u we're rear ended mybe it cracked Causing vacuum leak. Or maybe it's time for a cap n rotor? Best of luck man
