I have a 94' Mark and the tech needle sits at two grand and is taking a nap. Question is where does the tach connect? Also I'm getting a check engine light. I have a friend with a code scanner, when he connected it to the car, he said it gave him a air intake sensor code. "Whatever that meant". I just got the car in late 06' so now I'm trying to work out the bugs before the big P.A. meet. Any input will be considered.

You should move this to the Mark VIII section. You'll get better responce.
