Has there been anyone with the P0243 code in their T5 ????

sounds like a obvious TCV right ?

"easy" fix (if that what it is )

Probably not that but just in case test the tcv connector is well plugged in first.

now it just boost comes and goes ...erase CEL with a portable scanner and it came again acting even more strangely ....definitely the TCV my guess ....im on vacation so going to check that when in home....im also having sporadic CEL about the catalytic converter ... i think it is p0422 .. could it be sensor or catalytic ???????
