Loss of engine power
I changed my air filter and my 2009 gmc.
Shortly after check engine light came on as
well as loss or engine power. I changed it
back but I still have the same problem.what
did I do wrong?
Nothing unless you unplugged the MAF sensor..Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.
Thank you I'll try that after work.
