Help with values on obdlink sx
Hello. I just received my obdlink sx cable and used it on my 2002 tracker for the first time. There were two trouble codes relating to an oxygen sensor and a catalytic converter. I believe they might have been old codes since I had replaced those items before so I cleared them and there are no codes now. The issue that I am having with the engine is that something is not running right. it shakes alot while it is idling, specially at a stoplight forcing me to put the vehicle in neutral to compensate for the rpm drop from being on drive. The vehicle works fine while driving, it is just the idling. I was able to take a screenshot of the PID values and STATS. Can anyone tell me if these values look normal? Thank you

Unless it's a plugged up cat, those codes are really just for emissions. I can't read a PID from values, as I need an XY plot. I'd suggest you remove the O2 sensor, see if it improves the exhaust flow/performance. That would tell you if the cat is plugged, which is what I suspect.
