i just got my car back from the transmission place today!E-manage is installed correctly, the car is running great!no sputtering or nothing!but i do have a really low idle(around 200-300 rpms).I know that my Cat is clogged and needs replacing,i also need to get 2 new 02 sensors, and bkr7e spark plugs are gapped at .04 and ive been told they need to be at .03!!could any of these be causing the low idle???even tho it is a low idle,it runs fine!can anybody help!
