Q: Check engine light on

asked by on March 02, 2017

Brought to autozone for free diagnosis. Evap code. Told could be 3 different parts. I changed obvious one 1st. Gas cap. Still on. They said it's trial & error for the other 2 parts. Could be either one. Each one costs $99.00 Took to mechanic said charge $129 to find possible leak..that could be a pinhole in a hose. Sounds like a guessing game to me. Any suggestions would be appreciated. Thank you.
