First of all, this car finally runs fairly well. I have taken some fairly long trips and haven't had any problems.

Performance wise, I don't have near the same amount of acceleration as I once had (but the TCV was connected backwards no signal). When driving, the transmission doesn't seem to lock up and the rpms go high, but not much power until 4000. It requires WOT for decent acceleration.

I have no CEL, nor have I seen it in a while. Can the following components fail and not have a CEL? Catalytic converter, O2 sensor, TPS, transmission solenoids.

I have never cleaned the throttle body. Is that very difficult? Maybe I should do that next?

Bonus question: On a recent trip from Columbus, Ohio to Chicago, I noticed a constant scraping/screeching noise coming from my brakes. I could hear it on the highway with the windows down and in the city at slower speeds. I did new pads and rotors recently. What might be causing that? I noticed a groove in the center of the rotor.

I appreciate any thoughts.
