I Have 99 Grand Marquis Problem Pls Help!!
I Have 99 Grand Marquis I Replace All The Vaccum Seals & Replace IAC
Valve Still Getting The "Moose" Noise From The Air Box...Went To Autozone
And Ran A Diagnostic They Say It's An O2 Sensor?? What Else Can Be The
what air box ? did you replace an IAC valve to get rid of a moose ?
Where The Air Filter Goes In.. Yes I Replace The IAC Valve Moose Still There...
I don't think an O2 sensor would cause that , with many cars a code will come up but still run O.K. that's why you shouldn't take advice from someone who sells parts , is this something that was always there or did this start recently ?
The Moose Noise Wasn’t There Until I Was Relace The Vacuum Seals And The Hoses For The IAC.. And Once I Started 2 Clean The IAC Before Replacing It.. That Noise Became Unbearable Then I Replace The IAC Assuming That Wld Finally Work But Didn’t.. Now It’s Idling With The Moose And Somewhat Sputtering.. But Doesn’t Make Any Noise During Acceleration???
then you need to check your work more than likely
I Went To Several Mechanics I Know Personally They All Double Check Behind My Work.. And They Still Sent Me For A Diagnostic?? I’m Simply Asking For Alil Help..
