Are there any of you guys in the San Gab. Valley that are knowlegable in the T-Vis. I'm pretty sure that mine is always open. I'd like to have it woking properly... Vic

yep, i second the easy to diagnose part. its just a pita to reach up in there. if its not functioning theres really only 3 or 4 bits it could be assuming its getting a signal. you could replace any of those w/o pulling the intake mani. could be a s simple as a leak in one of the vacume hoses on it.
