What does SAFC stand for? wat does it do? did u get it? wat was the price? yeah i started to have the same issue as you 03 Corolla Sportivo, in the mornings when i start her, she coughs/chokes, but i just let her get warmed up and is all good.... cheers mario Id have to say I dont get any type of shoke or coughing ... What I do get when she is cold is a freakin loud as "sucking" ... like it just can get enough ... its like an vacume cleaner !
