03 Tacoma with 110000 miles that has developed what I have determined to be piston slap when engine is cold. First noticed it last winter and did not know what was going on then. If I start engine and take off with out a three minute warm up engine has a terrible hammer on acceleration. Once it is warmed up you can not make it to hammer no matter what you do. Summer time temperatures truck is ok. Has anyone else experienced this? Has anyone I have determined that I will just live with it and give engine time to warm before take off. Any thoughts or similar experiences?
