Here's one for the books....
So I checked the lines and wires again and all OK
Took it for a drive and under heavy acceleration with no boost, PO 243 came on
So I started to check the waste gate solenoid, wires, vacuum lines and found a mouse nest down under the brake vacuum where the thin white tube gets the vacuum for the turbo waste gate, low and behold the mouse had chewed a large hole on the line,I put shrink tube over it and went for a drive,WOW I now have a race car!!!
Hopefully this will be the end to all the check engine lights I've been getting!
