Check engine light came on while driving was solid left over night was on again this morning when I went down the block, then thought I would tighten gas cap I did then went to start it light not on
I was coming home yesterday around corner when
check engine light came on solid and stayed on till I
got home I thought leave it over. Night went out this
morning early down the block still on I then googled
possible causes and saw that a loose gas cap
could cause this I then re tightened the gas cap and
now the light is off Im taking the car to mechanic
tomorrow to make sure everything is ok but I just
want to know would this be the main cause I just
had a service a month ago aswell as a new battery
AC compressor and regas
