99 crown Vic sounds like foghorn ?

Asked by Sep 11, 2015 at 11:33 AM about the 1999 Ford Crown Victoria 4 Dr LX Sedan

Question type: Maintenance & Repair

Would a clogged trans filter cause this or is this a deeper problem ? Pretty
sure it's transmission related ; runs , drives and shifts fine . So recently my
transmission started making this sound , deep horn type sound ; every once
in a while at 1st , but pretty regularly now . Got a smoking deal on this car
when I worked at a dealer ,$1100 ; so I'm reluctant to spend a lot of cash to
fix it . Now every once in a while it will stall when I come to an abrupt stop . I
have put only 30,000 miles on it in 7 years , had 134,000 on it when I got it .
Been a great car , just can't see spending a $1000 to fix a $1000 car . Thanks

Possibly in the exhaust? Catalytic converter?

that is what i would think maybe a hole in the muffler exhaust leak

It does not always make this sound , and goes away if given gas . Don't think it's an exhaust related problem . I've had bad cats on my mustang , it would stall ; this is different . Thanks . I'm taking it to the mechanics in an hour to be diaged .

Let us know what you find out, hard to diagnose when you can't be there.

My son's car doing the same thing. No stalling, but it sounds like the horn is being used when he presses on the accelerator. This happens intermittently.
