a mechanic would probally know?

i'm getting really sick of my car problems. someone has to have had similar problems before.

SPECS

3.3L V6
AUTO
NEW ALTERNATOR
RECENT TRANNY FLUSH (LIQUID IS FINE AND SO IS LEVEL)
NEW PLUGS
NEW WIRES
NEW BATTERY (I THINK ITS BROKEN, BECAUSE I TESTED THE GRAVITY OF ALL THE CELLS AND THEY HOVER AROUND AVERAGE TO LOW, AND ALL CELLS GIVE OFF A DIFFERENT READING WHICH ISN'T RIGHT)

#1 PROBLEM
car runs like shit when cold. engine is all loud and whurrring (that has to be a sign of something, it only happens when cold)

#2
the car revs up when I shift outta park (only when cold)

#3
rotten egg smell??? i thinks its the caddy convertor

#4
listening to the exhaust, the engine sounds sputtery, is that makes sense. Again, like its misfiring. But with new plugs and wires why would this problem exsist?? could it be battery related??? or maybe a coil????


#5
I plan to totally wreck the transmission and engine because its under warranty, lmao, any tips on doing that without being obious?


lil help would be nice
:naughty:

One, what car is this?

As for the smell, that definately sounds like a cat problem. It shouldn't smell like that unless you're running straight pipes...

Don't know about the other things...

Reduced HP, and acceleration. The motor is basically choking on its self.

Does the car drive weird? Hesitation, can't get up to speed, wants to die when you give it gas?

Also have you replaced the fuel filter?
