Are you talking about putting it in your tank? or sucking it into the manifold?

Neither should hurt it. But why do you feel like you need to do it more than once in a while?

It works, pretty damn good too. Was just curious how often i could use it. This lean misfire while the engine cold **** is pissing me off.

It shouldnt hurt it, but Ive heard of it fouling spark plugs, so Id check them after using it. You think that Seafoam will cure your lean condition? I think you have another issue

Seafoam is beastliest **** of all time buy the gallon pour half it in your gas tank and suck the other half through your vacuums if that don't solve any problem you have concerning gunked carbs/injector/vacuums you have bigger problems and do so change your plugs it helps
