I changed spark plugs and air filter to my 2005 Highlander. Now Check Engine blinks 5 times and then the VSC and Trac Off comes on. What is wrong?
After around three days from the time I changed plugs and air filter, my vehicle started to idle roughly, especially while the a/c is on. Feels like it wants to die but it doesn't. Is car safe to drive? What could be wrong?
