Well, no wonder strange things are happening to your car..., your not supposed to be running 16 volts in it...When you step on the brake hold on to the volt meter with both hands or put it between your knees... dropping a volt meter is sure to kill it one day.... Where did Chivalry go, why are you not putting up your wife's window instead of making her do it ? Yes, you should shut the car off completely before you remove the keys.. in fact I can not figure out how to not do that...
UH,,, someone is talking to me in the background.. what ? OH... 16 Valves..... UH, Nevermind...
