Re: [DML] Accumalator

["Adam Price" <acprice1@xxxx>]

My car also began bucking this morning for the first time. Fuel is 
completely full and voltage levels normal. I put premium gas in it for the 
first time since I;ve owned it. I know these engines are rated for 91 
octane, but premium is 92. Could this adversely affect the engine 
performance?

Where is the inertia switch?
