Gruppe,
Does the 90Q ('89) have the capability to display fault codes? Are they the
same as the turbo I-5 (without the turbo related codes of course)? My
sisters car has a problem where, on the highway, under WOT the car will
hesitate above 4K RPMs. It feels like a flutter. I was thinking fuel
filter, but wanted to go the computer way first. Any thoughts?
Thanks,
Jamie
