Help please!
Ihave a 95 Esprit S4 with 9,000 miles and the boost indicator is gone crazy. I gives compleatly false indications I.E. bounces left and right no matter what I do to the throttle. I am assuming a loose wire around the sending unit. Where is the sending unit and what does it look like? Thanks!

On an SE (should be the same as an S4)the turbo boost gauge transducer (cylindrical) is mounted next to the MAP sensor (rectangular) on the same mounting plate near the ECU under the right fuel tank cover just ahead or on top of the right rear wheel arch. There is a vac hose from the orange air plenum that goes through the engine compartment wall connected to it. Also a vac line from from the vac pump should be going to the MAP sensor located on the same mounting plate.
Good luck,
Calvin

The Internet rocks. Problem fixed! The screw holding the ground wire was loose.
Thanks!

Good going. It's nice fixing something rather than paying someone a lot of money to fix it. Now spend the money you saved on some nice car car products and treat the car to extras or put it away in the kitty for the next time.
