Re: Spica car misfire

Hi Erik:

My first guess would be a clogged fuel filter; the one under the car before 
the fuel pump.  It's probably full of rust/sediment that becomes impacted 
in the filter after the pump has been on for a while.  With the car off, 
the sediment on the filter element loosens and allows fuel to flow 
again.  Sometimes, if you've got a good ear, you will notice a difference 
in the sound of the fuel pump when the filter is clogged.

Regards,

Dean
