Replace your alternator.

OK thanks so much and do the egg smell have anything to do with the replacement of the alternator

I would also like to know should I keep the new battery or can I put the old one back in since it wasn't the problem and get my money back


I would have the old one tested. They will tell u if you need to keep the new one. As for the egg smell, when a vehicle is running low voltage they don't smell great. Alternator should solve your problems.

That egg-like smell is the catalytic converter, when they go bad they can plug up, restricting the exhaust system and making it very to keep running, without riding the gas pedal. A temporary fix is to remove it but you won't pass smog emissions and you'll throw some O2 codes, the proper fix is to replace it but they're not cheap. As to the battery situation, go to any auto parts store, and have them run a free charging system test, then you'll know if the battery and alternator are good or need to be replaced.
