Going up a hill tends to drop speed, and if I press the gas pedal it will backfire.

May just be a tune problem, start here and run a diagnostics scan and if any codes are set post them here for further evaluation. not all codes will set a check light.

Hello ANTONIO SERRA,

I am sending you a link that if you decide to conduct the scan yourself it will be a great help to you. The link features an article with written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com
