I purchased my mustang not too long ago. I recently cleaned my iac and it was really dirty. I just wanted to ask about what other engine parts I can clean to maintain my car, also if there are any parts I should replace(123,000 miles) . I'm already replacing the fuel filter, things along the lines of that. I'd appreciate all your input and am really eager to find out more about my mustang!
Also, if you guys have any preferred cleaning products that would help.
