Better than a Bentley. Also (1) clean up all the electrical ground points
in the engine compartment. (2)Find and fix all the vacuum line leaks.
Chances are the vacuum hose between the Intake manifold and the lower
wastegate chamber is bad. Replace it with good heavy walled tubing. (3)Take
off the throttle switch, pop off the plastic cover, and resolder all 4
internal connections. Then replace the cover, seal it, and put it back on
the car. Your engine will idle better and accelerate much better. They are
ALL in need of this repair. (4)Find out when the timing belt and water pump
were replaced and get it done if the ones on the car are past 90k miles.
(5)Look over the front and rear suspension and identify damaged and
worn-out rubber bushings and replace them. At the same time, check the rear
transverse control arms for play. Probably needs new ones to hold
alignment.  Check front ball joints for same problem. (6) Get under the car
and check the exhaust bracket that hangs the rear of the catalytic
converter from the transmission housing. Mostly, they are broken and need
replacing. Failure of this bracket puts excess strain on the exhaust
manifold studs and then they break.

better if you traced the vacuum lines to the diffs, and found some leaks
and fixed them.
