  1. Incorrect valve timing
    Bad or too low of octane fuel
    Failed engine temp sensor
    Incorrect parameters set in the engines computer or add on computer.
    Loose hose connections form air filter/MAF sensor
    Bad spark plugs… cracked, closed gap, etc.
    Failing coil

    Is the check engine light on? post your codes in the comments.
