i have a 1.8L 4 cyclinder astra, my mum has a 1.6L 4 cyclinder astra
i drove hers the other day and it seems to have alot more grunt then mine
by grunt i mean applying less pressure to the accelerator but gaining speed faster/easier
hers is an 08 model mine an 06
do i have a clog or a pinch in my fuel pump?
why doesnt it have any grunt unless i floor it?
