CEL came on this morning, I have not had a chance to get the code read (might be a few days for this).

I haven't been DD'ing this car, my family has. What i noticed when I drove it though was idle was sometimes rougher that usual and that when braking to a complete stop the roughness appears for a bit.

Anyone able to help?

update: Code is P0135, will search the forums a bit

O2 sensor heater circuit bank 1 sensor 1

this could definitely cause rough idle
