Regardless of the reason why, this is serious and needs to be properly diagnosed and repaired by a certified mechanic. Once you know the problem you can then decide as to what do. Good luck.

Regardless of the smoking issue, a fire is a fire. The charges can only be based on a criminal offense such as arson or negligence. Accidents may not qualify in this category. That being said, the smoking ban rules and laws vary by state. You need to check state law for applicable statues in this area.

Hi. First of all, most cars do not go to 10,000 rpm. Six thousand is common. Are you asking something unusual is happening? It just could be the transmission shifting from one gear to another as the load demands are imposed on the engine. Please clarify the rpms as that might be relevant. oK? Good luck.

Hi. I would say no one really knows why JFK was killed. As far as I have found all presidential assassinations to date have been made, or attempted, by individuals with their own reasons. Regan's attempt was classic. One demented man looking to impress a woman. So I doubt if aliens was a reason or if there was anyone else involved other than the alleged assassin. You could provide for a theory of your own. I personally think it was the involvement against Russia or Communism since Oswald had been to Russia and seemed to have pro Russian feelings. But that is my guess. Good luck.
