g'day all

ok just finished the head changeover on my ea (it took some time i know)

turned it over and it's running rough but sounds ok at idel but while driving it's surging, and the temp gauge and speedo keep jumping all over the place.
the breaks are tough to use now like there's no vacume behind them.

any help would be apreciated

88 ea 3.9 cfi dule fule everything else is stock

although it hasn't been run on pertol in a few years
(previous ownre disconected the fule pump) so i'm guessing the carby needs some work.


thanks

Can you go back to gas, to see if it is ok on that.

won't run on petrol (guessing the injectors need to be uncloged)

so right now it's only running on gas

see if you have got all the earths on. and see if all vacum lines are on as well .keep us posted

where am i looking for the earths?

and all vacume hoses that i disconected were hooked back up to the same spot


update:

been back over evrything and i can't see anything that's not connected

sounds like a vac leak, get a spray bottle of water and squirt it around the inlet manifold and any vacuum lines while the engine is idling and listen for a change in engine speed cos if theres a leak it will suck the water in. also follow the thick vac line from the brake booster all the way to its end and make sure its connected.

yep vacume leak it is lost half the thread on the vacume cupling (white plastic thingy) on the inlet manifold

$16 from ford for another plastic one

Anyone know of metal ones being used and if so where to get one in brisbane?

thanks for the help
