Q: Knocking noise in engine on 2004 Jeep Liberty

My 2004 jeep liberty has a flashing check engine light and there is a knocking noise prevalent when pressing the gas pedal. Power is lower. I can also "feel" the knock in the gas pedal. Any ideas?

TOW........flashing check engine light means damage to catalytic converter(s) along with other internal engine parts , but from your description , it sounds like the damage is done. Good luck.
