FD is bucking, backfire's and running lean
Hey guys,
So since recently my FD has started bucking quite heavily whenever I go off light throttle. Another thing that is starting to get worse and a bit annoying is the backfiring whenever I go off throttle at low RPM, I'm not sure this is normal but there really is a lot of popping in the exhaust.
And lastly, I have replaced my O2 sensor with a new one, old one was completely white, which I believe indicates a lean mixture.
Now my FD is a 95 JDM, it is completely stock except for a Catback. Could these issues be related and if so what might be the cause? Other than these issues the car runs and drives completely fine.
Aad,

It happend after i changed plugs and wires, if i recall correctly i did unplug the connector on the tps when i did this. Since then especially the backfires are gradually getting worse, i.e. more frequent.

Little update, I have checked the TPS and found it was a little bit out of spec. After adjusting, the backfires and the bucking have almost completely dissapeared
