1992 Cadillac DeVille 4.9 from North America


I love it!


How do you up the idle on my 1992 Cadillac Deville? It's idling too low.

Other than that... it's wonderful and her name is Charlotte. One owner car and it's never even been dirty inside. The old guy kept it like new. Wow. And she only cost me 1,200 bucks. Yay for me.

The only problem is the windows. Wires shorting out on the drivers door. Messing up the windows.

Usually these particular Cadillacs need a few things that can be accomplished at most basic mechanic shops or DIY stores. Most of the fixes are cheap. I have maintenance comments posted, search: 1990 Cadillac DeVille, Edmunds (look under reviews).

First replace the PCV (pollution control valve) $5.00 part $7.50 labor. Open up the air filter box, remove filter, start car, spray seafoam ($9.50) injector cleaner inside slowly to help clean throttle body, combustion chamber and fuel injector. Upon completion, replace the air filter, if dirty, reinstall air filter and close/fasten filter box.

Great cruiser for someone who maintains it like a luxury car, even though it is equipped with a 4.9


Rear shocks & struts need to be replaced around 130000 miles.

Not gas efficient (16 to 18 city, 24 highway), it's in your best interest to use premium since it is a 4.9, it will burn cheap gas noticeably quick.

MAP, TP and O2 sensors pop codes intermittently due to loose wires or needed replacement. Always check sensor connections before replacing them, average mechanics will insist replacement. $150-300.

Badly designed oil cooler hose location, prone to crack and leak onto the manifold, which disrupts the 02 sensor's output = bad fuel economy, overheating.

A time will come when you must keep the gas above a quarter tank due to faulty design and placement of fuel pump, otherwise during right turns the car will stall and imitate a slipping transmission until the gas balances; a bad experience to deal with in rush hour traffic merging off a cloverleaf. It also will sputter and die, even though the the dash says 2 gallons - ON'T WAIT TILL IT GETS DOWN TO 2 GALLONS!

Around 130k miles paint begins to peel on lower doors, however it's quite resistant to rust.

General Comments:

Overall great cruiser, very comfortable, quick, retro classy and a head turner. The 4.9 engine lasts forever if you keep her maintained. I'd choose the 4.9 over the blown head gasket prone Norstar any day.

Had the same problem on right turns. Replaced the fuel sending unit and haven't had the hesitation issue since.

Love it and will miss it


- Oil line to radiator was leaking, cheap and easy fix.

- Original alternator died around 180,000 miles.

- After being cut off and slamming on the brakes, one of my brake lines blew off the brake itself.

- Occasionally I would have issues with the accelerator control unit, and the car would idle too fast; tapping it with a hammer would generally fix it (classy)

- Thermostat went (this was the only time I had to get towed)

- As of recently the wiper switch stopped working and the part is roughly $300, labor not included.

- Also in recent months the air ride suspension has started to act up; it is most likely a leaky line to the air cylinder.

General Comments:

This was my first car, and it has been my pride and joy. I've been into Cadillacs for a long time, and know that many of the vehicles Cadillac produced between 1980 and the present day are anything but reliable.

This car, however, and any Cadillac with the 4.9 engine, is EXTREMELY reliable. This is a great looking vehicle with plenty of power.

Driving this car is unlike any other car I've driven; it glides down the road with plenty of power and acceleration.

The interior is obviously comfortable and roomy; it's a Cadillac. Lots of storage room (once fitted a drum set, three amps, two guitars, a bass and three people in this car with ease).

I used this car as a daily driver since I bought it, and the past two summers I accumulated a lot of miles driving to and from job sites (8,000+ this summer alone). I also used this car to get me through a year and a half of college.

I unfortunately have to sell mine because little things are beginning to go wrong with it, and being in school, I have neither the time or the money to fix the little things. But if you can find one of these cars in good condition with low miles, you will not regret it as a daily driver or as a weekend cruiser.

If you love Cadillacs like I do, and don't want to restore a classic or spend five figures on a new one, then track down a late 80's/early 90's caddy with a 4.5 of 4.9 motor. Stay away from the the Northstar, far far away.
