I'll be out doing some testing but wanted to make sure I have the right train of thought.
I was running rich and diagnosed a bad o2 sensor (stock). I replaced it and my AFR's, as noted by my AEM wideband, got better but not great. As I drove it for a bit I noticed that on decel with foot off the accelerator pedal I would still get some rich readings, around 13 or so but if I am not mistaken my AFR'S should go completely off the chart lean as the injectors should be off. This is the case with my 1g but not this car. Obviously there could be multiple reasons for this but let's cover all the bases.
I am going to start with these
Possible issues....
IPS not working ( 2g TPS)
Stuck open injector
Bad valve seals
Turbo seals leaking
Anything else I should check?
Thanks
Just for info this is in a 93 colt Vista with a 2g 2.0T swap using a 98 ECU currently.
