Question about Saturn Ion
We recently had the oxygen sensor replaced did this possibly cause the racing inthe engine while trying to brake
This has always been a nuisance to me. My car often downshifts to a lower gear when applying the brakes. This happens much more when braking sort of hard while going downhill to a stop. Downshifting uses the engine for braking, and in the process revs the engine. A very stupid setup! I'd rather replace brake pads then to put that extra stress on the engine. I've been looking for a way to disarm this *feature*. I don't have the schematics yet but I'll bet a braking signal is sent to the main computer or the transmission computer.

No O2 sensors don't cause any kind of issue like idle speed concerns, I have 30 years of expeariance to back me up on this
