It sounded like they were talking about the one on the engine. They want some were around $1k to do it and I asked how much it would be if I skipped the intake manifold gasket and they said they have to take the manifold off when they replace the harness any way.

I was hoping I could do it myself cuz I'm in collage and have no money so my dad would have to pay for it and since he already says I need to look for a new car cuz this thing gets only 12mpg, so he would probably not pay for it and say get a new car.

I wish I had the car here so i could look at it and get an idea of how much work it is but I guess I'll have to check AllData next time I'm at school and see if it lists how to replacing the harness.
