Everytime i pump gas my car starts up then my idles like i got some huge *** cams, but i have the crower ST 2's then it goes away, but it always happens right after i pump gas...it makes my car sound like boop,boop,boop,boop...like an american muscle car. does anyone know why??

 

anybody???

 

First thing I'd do is check fuel pressure before/after filling. If you have some sediment in your tank you could be mixing it up when you fill, which could be causing fuel delivery problems and your described rv cam idle. That's the only thing i can think of which would be affected by filling your tank.

 

thanks
