2004 Cadillac SRX in park, engine goes from idle to racing 3,000 rpms. Also while driving and coming to a stop and then starting off car won't go any faster than 10 mph, gas pedal doesn't work at all when that happens. Even stopping and turning

Everytime I pump gas my 2004 cts won't start it will just crank and I have to recrank it several times till it starts but when it does. It starts with a faulty engine until I accelerate then it acts normal. I need help a.s.a.p please..

my 1999 cadillac deville starts and runs  but when engine gets warm the engine shuts off but  I can start the engine right back up and when stopped at a  stoplight the engine shuts off but will start right up.

around.There's no leaks ,but car does sligthly get hot after driving about 30minutes
yet when I check car underhood engine doesn't appear to be overheating.pl
