just wondered if anyone could spread some light on a car i brought today.the car misfires fairly bad before it comes on boost.iv checked the compression on all four and everything there seems to be ok.i also checked to make sure its sparking correctly and that seems to be ok and pretty sure its fuel now but was wondering if anyone had any idea

 

change the plugs?

 

tried new plugs leads dizzy cap and rotor arm

 

must be fueling then its just locating what init? good luck m8
