I have just completed a quite an extesive rebuild on my 6cyl EF, Before and now even after the rebuild I am getting a slight (sometimes quite bad) hesitation while accelerating at roughly 2000rpm then after a couple of seconds it kicks in.

Now I have retained only a few things from the original engine (injectors, inlet manifold, fuel pressure regulator, MAP sensor) but all sensors and electrics (on engine) are new.
Fuel Pump is only new aswell.

My suspicions are injectors or MAP.

Any ideas??

how is the dizzy? rotor button both the contact inside and on top. dizzy cap centre contact
plus 6 contacts also leads test and check for breakes, earthing out while running see a spark...
also tpi shake the wires while car running.. if the tpi is playing up that will normal show it.
if it was fuel it would do it all the time.... the map is a good ghess too. clean vac tube and
test with known work map...

Dont have a Dizzy.. Cheers anyway.


Well its just one of those annoying things I guess.. I will probs swap out the MAP and some other things from my girlfriends EF next weekend and see if I find the issue.
