I agree. And another signs of loose compression if U're not a professional mechanic, the idling of the vehicle is ERATIC. Meaning, sometimes normal afterwards low or high. Next is the tail pipe of the vehicle, a white smoke is coming out. The ERATIC idling of the vehicle is very noticeable when U switch on the airconditioning unit of your vehicle. To the extent the engine will die down. Furthermore, use also vacuum tester. Said tester will also help U and confirm the condition of ur vehicle.
