The dealership says I need to replace the entire gauge console ($500) to fix the speedo. (wondering if they are right, or if they want $$. You never know..... After hubby working on the electrical it works about 70 % of the time. It bounces frequently.

The check engine light only comes on when the gas gets below 1/8 tank (not each time, but on occasion). It goes out when gas is put in it.
