Well, after reading all the things people are having trouble with on their calibers, I've been keeping an eye and ear on mine. I'll be having the dealer look at the exhaust pinging, dash vibe, and w/w nozzle on thursday. Today while driving, i decided to open up the windows and really listen to the engine, since it was hot out. I noticed that when i accellerate, or when the engine is under load, it sounds like it's dieseling a little. I've never heard spark knock, so could this be the warm weather spark knock? I'm running 89 right now (dealer paid for the fill up, why not upgrade a little?) have 1250 miles on the car, 2.0 w/CVT. Should I get it flashed while it's there? The power is great, and I don't want to ruin a good thing.
