Drop the exhaust from the car...that will tell you real quick if it is the converter or not.

I'm starting to think we got more than just one problem going on, and it'* going to be difficult to give a good diagnosis.

No need to do a full drop. Just undo the downpipe from the manifold, and undo the hangers near the cat. The exhaust should swing out enough to fully disconnect from the mani.

On my 88 Lesabre. I incorrectly condemned the cat for a clunking rattling noise when it turned out to be a broken off timing chain tensioner pad, the metal part left digging into the chain, and tons of slack in the chain. this was at 162,000 miles. It never jumped though. I don't know if Series 1 tensioners are different than 88-90 motors. Mine had a 1x1 square block tensioner pad.

You have a different motor, a different tensioner, and are the only case of your generation to ever have that failure that I've heard of.

Making such a broad statement that would require the topic author to pull a timing chain cover with a mount in the way that you don't have........

Discuss it as a possiblity. Not as a 'norm'.

Well....More Problems::::

This Car Was Starting First Time, Everytime For About Two Days
I Again Parked On A Hill (My Driveway) With The Front End Being Lower
Then The Back But I Turned It Off This Time And It Will Not Start Again
Now It WON"T EVEN TURN OVER> !!!!!
I'm Starting To Think This Is All Caused By A Fuel Problem ?

and while parked on the hill i happened to jump up and sit on the
hood latching it close and when i tried to pull it open with pliers
like i did before i pulled a little too hard and snapped the wire off
so now i can't get the hood open and to top it all off its hooked up
to a battery charger

Before being put down for a few months after this problem started my mom changed
the:

water pump
electronic lines to fuel pump
security system
ignition
spark plugs/and wires
crank sensor
o2 sensor

i rensently changed the:

Battery
Altenator


Mechanics are saying its either:

the "Brain"
a sensor in the dash :*
injector "controler"

My Guess:

Fuel Pump
ICM
MAF Sensor
Injectors



(mostly quoting my mom
she don't know the REAL
name for anything)
