Hi Guys
So today I did an oil and filter change, I also cleaned the air filter out and put on a new top hose for the radiator and flushed out the old coolant however now the check engine light has come on as well as the cruise light keeps flashing, I'm not sure what I could have done wrong or if maybe I've hit a cable somewhere but the car seems to be running properly so I'm not sure where to start looking, any ideas of what could have gone wrong?
Cheers
