Why will my transmission not engage
Low on transmission fluid , Shift cable broke , internal problems , fluid pump worn out , Unless you rebuild transmissions for a living ( went to school to do it ) your best bet is take it to AAMCO or dealer !
2002 Cadillac Seville sputters
It is probably related to the fuel injection system. If it were old, it is similar to a choke on a carburator. Try putting some good fuel injection cleaner in the gas. If that doesn't work... take an air hose and blow out the circuit which is accessible through a plate by the butterfly air inlet. You can also spray carb or brake cleaner to unfoul that system... but it will smoke for a while.

Put in a fuel injector cleaner such as Lucas. Use a higher octane gas. 91 or more. After a couple of tank fulls the Knocking should go away unless you somehow bent a pushhrod. Did you replace your timing belt/chain recently??
If not use a higher octane fuel
Sputter rpm
When a car warms up it enters closed loop state. This is when the computer uses the sensor inputs to adjust air/fuel ratios.
MAF - mass air flow sensor - These can be cleaned.
Oxygen sensor - Usually when they fail the mixture gets richer. I think yours is getting leaner
Camshaft and crankshaft position sensors - They can be affected by heat when one is failing. They provide the computer with timing information
An obd tool that reads real time data would help narrow down the problem. You can get an elm327 usb to obd connector on ebay for $10. Then get free software to read the car computer with your computer.
