hey guys wondering if some people can throw out some ideas on why my 2013 commander 1000 xt with 850km on it has check engine light on and low oil pressure. i changed the gear box with proper gear oil and engine oil with 4 stroke synthetic 5w-40 (twice) on accident haha pulled the wrong plug to change the gear box oil which ended up being the engine oil drain plug(a different one from the first time i change it). the light and message turn off when i rev engine to 3500 rpm and come back on when i let it idle. the light and message come on most of the time but not all of the time as soon as u start the engine and will come one soon as engine starts to warm on. thanks for any help and advice.
