Cadillac: I Expected More !!!!

The 1996 Cadillac SLS produced 275 Horsepower @ 5600 RPM and 300 ft. lb.
torque @ 4000 RPM. It was the STS that produced the higher figures.

That being said, when looking for power in your car make sure to account for
all the basics first. I'm eternally amazed at what gets overlooked because
it's too simple a solution.

1) Plugs/Wires
2) Air Cleaner
3) Fuel Injector Cleaner

Has the transmission been flushed and cleaned out recently? How about the
differential? Icky goo in there only adds friction, and friction robs power.

Also, it has 110K miles on it, have you checked the cylinder compression
yet? Depending on how well it was maintained you may have compression loss
due to worn rings and the like.

Cheers!
Jody

You shouldn't get even five or ten feet of rubber, with the traction
control and all. The egr is full electronic and if it had a problem,
it should set a performance type code. It will either stick closed, or
stick open. Elaborate on the 'idles like a rock', is this a good or
bad thing. The transmission is adaptive, if Grandma has been driving
the car, then it will think Grandma is driving the car until it learns
different. How does it accel when it is manually shifted through the
gears? It is an SLS which is going to deliver you a bit less
performance than the STS. It could be a little choked up with carbon
as well, a lot of people don't drive these cars like they need to be
driven. If at higher rpms of hard accel, you see a trail of gray sooty
emissions, it is carbon. Check the plugs, found to run best on ac
delco platinums. Use a good brand of mid grade fuel as well. Have the
cooling system tested for presence of combustion gases.

Thank You both very much for the tips and info.......I will be giveing
the car
a good going over this weekend .......plugs wires air filter etc .ill
let you know how it goes
As far as it "idles like a rock " i meant it shows no sign of skipping
or misfireing .......thx again

I too have owned and been involved with muscle cars for entire adult life.
My wife has a 2005 STS, with the 320hp northstar engine, which is some 45+
hp more than your 96 SLS. Designed to be Caddy's top of the line 4 door
performance sedan, the STS is very quick for a heavy 4 door luxury sedan,
loaded with options, but at my 5,500' altitude, is some 1-2 seconds slower
0-60 and 2 seconds slower through the quarter than my stock 305hp 2000 LS1
Trans-am (5.1 sec 0-60, 13.6 sec, 106mph -quarter mile). Even though,
compared other 4 door luxury sedans it is outstanding, I'd of been quite
surprised had the Caddy come any closer to the T/A.

You are trying to compare apples to oranges. You didn't buy a muscle car,
you bought a performance oriented, quite heavy luxury automobile. It should
compete quite well with similar year Beemers, Lexus and Mercedes, which,
inspite of all the bullshit they put in their advertising, are not muscle
cars either.

What were your 0 to 60 and quarter mile times compared to you old Caddy? I
think the seat of the pants difference you perceive in performance between
your old caddy and your new one is just the difference in ride and sound
proofing a newer caddy enjoys over the old runs. Go stomp on a old rattlely
'59 Deville hard top or 'vert and it will sound an vibrate the seat of your
pants like it is going a heck of a lot faster than it really is.
