2007 Honda Civic

PLEASE READ! recently bought this car from another person, for my son as his 1st car. since I purchased it, I had a new kenwood deck & alarm installed; brand is Compustar which also i have linked to the drone app for tracking etc - tho it comes with its factory alarm already. I've taken the car to Honda, had them do a general inspection along w/ getting spark plugs changed out (has a 1YR warranty), oil change, cooling system cleaned out, yet was told there is a "timing chain cover leak". Time to time car boggles out while driving & the check engine light comes on - not sure why, Honda cant tell me either, goes away & drives fine after turning off. Besides that I got minor accessories for the car itself ex, all weather floor mats, new E brake cover w/ steering wheel cover, also the interior detailed & cleaned & has been kept clean since & only drove to & from work since purchased. Looking to sell NO TRADES Serious inquiries only - cash up front! haters will be ignored
