#1889 of 2635 HELP! What could this possibly be?
Sep 16, 2005 (12:20 pm)
Hello, I am posting this in hopes of getting some answers as to what this problem could be with my sisters car.
She has a 1992 Cadillac Deville and the car seems to "lose all power" at times when driving. When this happens she can pull of the road & sit there a few minutes & let it cool down and be on her way. This seems to happen only when it is hot out & her engine gets hot. She has been calling it vapor locking, but I'm not quite sure that is what it is. This week it has happened over the past 3 or 4 days. Other times, it won't happen for a month or more.
My husband has looked at the car & can't figure out what it is. I do know the thermostat has been replaced. My uncles computer you can put on a car won't/doesn't show anything when ran on it. And there are no check engine lights on.
This car was my grandma's, I believe she bought new or fairly new. She then sold it to my mom who then sold it my sister. So it's been in the family for a couple years, to say the least. And has not been drove hard. To the best of my knowledge I believe my grandma had this checked out when she owned the car b/c that's when this started happening occasionally. Then my mom bought it off her & she lives about 2.5 hrs from where we live & when she would come in, she would have to pull over sometimes 4 or 5 times or more b/c the engine would get to hot I guess & it it would lose all power.
Anyone have any suggestion as to what this can be? My mechanic hubby is stumped along with my uncle who owns a garage. They can't seem to think what the problem could be. Though they have not worked on many cadillacs, could be why.
Any help would be GREATLY appreciated! Thanks in advance everyone!

A few thoughts.......NO codes......Dying when hot............
Where do you live ? If snow, ice and salt land a rotted gas line may
be the cause of your problem. Even a garage kept, lo mile car.........
A crank position sensor is another..........Common failure item.
Will throw no codes.
Has the cat converter been checked...May be plugged.
Fuel pressure regulator........Another common item.
Easy to check.........Just pull off the vacuum line. If the line is wet...
Open your e-mail addy (in profile only)...........I have a few more ideas

Concours.............They are hard to find. I think the "oldsters" didn't
like the buckets and floor shift idea not to mention the $$$$ over
the price of a base DeVille or Fleetwood. So not many sold.
When were they made? 96 thru 99?
Me...Still on the hunt. Sure is a chore rowing my own gears.
Gas has dropped almost .50 cents a gallon in the past week so it makes fueling my truck easier!

Yes, the Concours I am looking for was made between 96 and 99. They actually did some tweaking to the 97-99 models which made those years much more desirable than the 96. One disadvantage was that the Northstar of that vintage only ran on premium. I have yet to use 87 octane fuel in the 2004 but like having the option if gas prices keep rising. I saw a base Deville in gold on Friday and it is
to my taste a much more attractive car than my 2004 in light bronze mist. My 98 was also a gold and really a beauty. Am happy to have the 2004 model with features like Onstar and improved handling but wouldn't mind having the older model if I could find one in good condition and at the right price now that my larger garage would fit both cars.

BTW..........Currently in NJ on a roadtrip. Seems my cruise has
"healed itself" or I am getting better setting those confusing
steering wheel controls. Cruise ran rock hard steady thru the
hill n dale of NY, Pa, and NJ....................
Wish they would move them to the top part of wheel and put
the radio or onstar buttons on the bottom !!!!!!!!!!!
Hows your cruise been doing?
After my 96 it is a treat using 87 in the 03!

Ok, you should be able to email me now through my profile.
We live in Huntington, WV, so we do get some occasional snow (maybe like 2 or 3 inches at most the past 5years), they do salt the roads if they think we'll be getting any snow, and we do get ice, but not bad.
I just spoke with my sister a little while ago & she said she went to put gas in her car and at 8 gallons it kept stopping like it would if the tank was full. Her gas gauge when someone had replaced the fuel tank I'm guessing, is a little off, and so her "empty" line is at 5gallons.This is the 1st time it has acted like it was full & wouldn't take anymore gas. She did eventually end up getting gas in it.
Thanks alot for all the help & suggestions

Cruise control is working about the same, I have become accustomed to the lose
of about two miles an hour after I set it so I generally am prepared to hit the accelerate button once or twice after initial setting of the button. I watch for traffic behind me just in case it fails to take hold as it sometimes does. While I am living with it as is at some point I may try to resolve it with the dealership which has had it three times and could find no problem. Suspect it may be a defect in the buttons on the steering wheel. The service department of the local dealership here is not all that great and the next nearest Cadillac dealership is 125 miles round trip. Most of my driving is short trips, if I were to plan a long trip would probably give one of the dealerships another try at resolution. May call Cadillac Corporate again, they were not much help in the past.
I have not tried 87 octane gas yet but from what you have reported I am encouraged to try it if prices continue to rise sharply.

OH YEA....................87 will run fine.....Not a problem running it
compared to my 96 prem. only model. The 96 would buck, stall,
and ping on anything but prem.
25+ mpg. to boot !

Do you get the same performance out of the Northstar system on 87 as you get using 91? While I know it will run on 87 was wondering if I would get the same acceleration on 87 as I get on 91?
