The car has just started doing this again where it feels like I'm driving with the Handbrake on in all gears.
Boost pressure is still normal, engine idles fine and still seems rev normally in neutral, it just feels like under load the power is getting sucked away. & more so as the revs build.
Would rather fix it before it completely dies and leaves me stranded somewhere..
Standard repairs previously completed & hopefully to be ruled out are re-built alternator, Starter, & replaced Leads & water pump.
Any ideas??
