why did my check engine light come on after I had my spark plugs changed and added gas treatment
4 Answers
because the car was not turning over the 1st time I tried starting the car so my mechanic said put gas treatment- I only use 93 supreme
The mechanic had just finished putting my spark plugs in that day
Go to AutoZone and have them scan for the code for free and see what the cause is... Then you willl have a good starting point... It could be a number of things going on with your car...
