Re: [doc] Misfire Under Accelaration???......

Good Points...will check the kink in the fuel pick up first... i had 
to rotate the pump 1/4 turn or so as a last resort....just to get 
the hoses on the top of it to fit behind the bolt off 
panel....thinking this may be the cause :).... fuel filter next then 
injector cleaner!

Cheers 

Mike
