Well, check engine light is on and my obd2 is reading error when I diagnose it.
I'm loosing radiator fluid slowly, and my engine starts with a flutter only when the engine is cool. Also when when in drive gear once its warming up, the motor jerks like the gear is sticking. But once it passes that point it's fine.
This only happens when the engine is cool and I'm warming it up to drive like in the morning time.
It did have head gasket leak but I used that head gasket sealant stuff if it seemed to work cause I don't get white smoke nor is my oil cap gunked up.
I do have a minor valve gasket leak which oil drips on my manifold to cause oil burning smoke.
Any opinion on my engine may flutter like during turn key start or why I maybe loosing minor radiator fluid.
I think it maybe a cylinder misfiring but what do u guys think. Thanx

Sounds like a head gasket is leaking antifreeze into the combustion chamber. Do a pressure check on the cooling system.
