Rather than guess and fit parts not needed , besides the cost , get it scanned with Tech 2/3 for better reading of fault codes . Sounds like a vac leak somewhere ,could check the PCV valve . Petrol smell could be many things , low compressions , injectors over fueling .to name 2

Any decent scanner will do and someone trained to read it.
Sounds like you purchased a faulty car that was going to be a "cheap fix".
These never are.
The 1.6 did have throttle body issues and egr issues so don't guess. These are all expensive parts. Test first... Then replace.
