First do you have a sterring wheel puller. Can't remove the steering wheel without one. Quite an involved job including snaking the electrical connector end through the steering column. I wouldn't recommend it to the novice

a drain pan, a hose release tool, flare nut wrenches and simple hand tools, such as a set of wrenches (sae and metric) and sockets with a variety of extensions. it would be helpful to have both 1/4" and 3/8 inch drive sockets and ratchet's

On my car, which is the same as yours, it is located on the manifold top back left. Pictures in the book just show it on top.

My 1997 Cadilac Eldorado touring. the MASS air flow sensor (MAF) IS plugged up. the car starts up and cuts off immediately unplug it and idles high and then cuts off what could this be?

THE MAF IS NOT A TOY OPTION ON ANY EFI ENGINE.
YES MAF DOES GET DIRTY AND WE USE MAF CLEANER TO CLEAN THEM (SPRAY BY CRC MAKER) DO NOT LET THE SPRAY TIP BE LESS THAN SAY 10 "INCHES AWAY 250MM. OR THE HOT WIRE INSIDE(SENSOR) WILL BE WRECKED.


UNPLUGGING THE MAF FORCES THE PCM TO GO TO LIMPHOME MODE. + MAF SIMULATION MODE.
CRUDE:
A VARY BAD THING WITH HUGE FUEL CONSUMPTION AND BLACK TIPPED SPARK PLUGS
AND LOSS OF IDLE CONTROLS

LIMP HOME IS NOT FOR DAILY DRIVING EVER.
IT IS TO AVOID AN EMERGENCY ,SAY STUCK IN A SNOW BANK AND NEED MOVE TO SOMEWHERE SAFER. NO OTHER PURPOSE.
CLEAN THE MAF
OR BUY A NEW ONE
LIKE EVERYONE ELSE DOES LIKE THIS.
GEE IF YOU SCANNED THE Pcm AND IT TOLD YOU MAF IS DEAD, WE REPLACE IT IF CLEANING DOES NOT HELP IT.

HERE THEY ALL ARE FOR SALE

Location of the mass flow air sensor in a 2007 Cadillac SRX? how to replace?

Hard to believe you have a bad MAF in a 2007 caddy. How many miles on car? Have you tried cleaning the unit?

Parts store have a locator chart which should show location.

1992 Cadillac Deville ideals really slow and miss's when I step on the throttle

Do this frist and then if the miss is still there have the spark plugs and plug wires replaced.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Try checking the throttle plate in the throttlebody. Pull off air intake hose and see if there is a lot of carbon buildup on plate and bore. clean with throttle body cleaner CRC makes a good cleaner that won't hurt your sensors.
