Engine Mechanical problem
1990 Cadillac Deville V8 Front Wheel Drive Automatic 180000 miles
Cadillac dealer says I need air diverter valve. Part# 17090215.
So far no luck in finding one. GM out of stock.I hope to find aftermarket one.
Any ideas where I might find the part.
The dealer took it apart and broke it before they found they couldn't replace it.
There is now a loud exhaust noise on acceleration.
Also could use diagram of part so I might see if I can make it quieter.
I've put a lot of new parts in the car and it ran great before the broken part.
I should have just kept running it with the "Service Engine Soon" light on.
It would be great if you can help.
have the same problem?
