Car used to have a decat and I replaced it with a standard CAT, after a few miles the emission light came back on.
Secondly, I used RSTuner and loaded on the remap, ever since then when accelerating slowly or even trying to hold a steady 30 in 4th or similar - the car is very jumpy and doesn't feel right.
All plugs and leads were changed not long ago. I would guess the emission light is the O2 sensor after the CAT? Would this also cause the second issue or is it likely RSTuner related?
Thanks.
