I had a Mustang that was missfiring. Went to a couple of shops to see if they can fix it.
One shop said they can't help me because the "check engine" light is not on. Another shop
replaced a few thing but still didn't help. I read positive reviwes about Gene's Auto Repair,
so I decided to give them a try. They fixed it. Gene said that using some kind of mode 6 he was
able to see which cylinder missfired and replacing ignition coil solved the problem.I dont think
my Mustang ever ran as good as it does now. I am very happy with Gene's.
