1.Jack up the vehicle
2.Place a rag under the supercharger bolt hold you will remove
3. Remove supercharger bolt, some oil may come out but not much.
4.**** out the old oil
5. Lower the car back down
6.Fill the supercharger oil
7.First time driving after change

the oil level sensor in the oil pan is probably going bad.

Hello lysiphlebus2,

((My thoughts: cold START valve IAC at very bottom))

Plenty of places will do FREE diagnostic code reads.

I would rather suggest it be a muffler shop than
AUTOZONE... but either is better than guessing.

AUTOZONE will likely make you buy OXYGEN
sensors... (but that makes about as much sense as
buying a new THERMOMETER every-time you
have a FEVER.

What you are describing sounds (from an old
mechanic's perspective) like a collapsing
catalytic convertor or rotted muffler baffle
(a slightly better blockage will halt operation
completely)...

((again speculation... get your codes read))...

Do not buy OXYGEN SENSORS....

Know your prices before waltzing into any
exhaust shop.

I do mine from underneath, Its the easiest way! At least I think so. Just make sure you use jack stands or some heavy duty ramps.

If i remember right you have to remove the oil pan,then you have the filter inside,remove it slovly or you will have oil everywere,put a bucket or something under.

you will most probably need a beefed up tranny to take the power of the engine, I have just installed a 350 supercharged chevy motor in my sons car with a Turbo 350 transmission and a shift kit which I have been told by an auto trans mechanic may not take the power of that engine.
It is costing him $1500 australian to have it reconditioned so I hope it will survive the rides

you can not put a regular 3800 intake in place of the 3800 super charged engine,the compression ratio is lower than the regular 3800 engine.......!

if you look on the top of your supercharger, you will see it. u have to get it out with a hex screwdriver
