A couple of things...

Ok, my 88 EA S Pak drinks more fuel than I do beer!
Im at my wits end....got new dizzy cap, rotor button, plugs, leads, air filter, fuel filter, oil filter, XH Snorkel :), still fuel consumption must be around 20l/100kms!!!
Diagnostics ignition on and engine on both call 22, MAP Sensor.
Would a MAP Sensor cause such high fuel consumption? I have folowed the Gregories and checked for 5V at the relevant connector on the MAP. Its getting 5V like it should. Most likely its internals arent doing what they should? When I unplug the MAP, the revs rise slightly at idle, and idle is a little rough. But who can argue with diagnostics, both modes!
Next, a one of the little gears in my speedo has lost some teeth, can I order a new one from ford, or will I have to fork out for a new speedo? Chances are if I want a speedo from a wreckers, they will want me to buy the whole dash!

Go to the wreckers and get a MAP sensor off an EF. Should be the same as EA. Shouldn't cost much more than $5 so you won't loose much if it turns out that this wasn't the problem.

Another thing that causes excessive fuel consumption is running the engine too cold. eg. if you remove thermostat.

Got another MAP from wreckers from an EA, for $22.
Replaced it, diagnostics STILL calls bloody MAP!!!
Should the callout dissapear when I replaced the MAP sensor, or do I have to reset the ECU or anything?
I am going to reset it tonight anyway, see what happens.
I Just dont understand it!!

If the idle quality changes when you unplug it, I'd guess the MAP is working - have you tried making sure the vacuum line is clear? Also, you could try picking up a spare fuel pressure regulator from a wrecker - DON"T go back to the prick who ripped you off on the map sensor! :) If the fuel pressure is too high, it can cause overfueling....
About the speedo gear - I presume in the dash cluster? Either pick up a dash cluster from a wrecker and gut it - he'll probably give the thing to ya, they're worthless - or I'll send you the bit you need in the post if you like, I've got a dash in pieces already.
Good luck!

Thumbs up

Hey mongrelEB, thanks for the reply!
I sent you an email if you could check?

Fuel presure regulator may be worth a try if I can find one cheap.
I am very close to taking his thing to Ford and telling them, FIX IT!
If it doesnt cost too much!
When I removed the old spark plugs, they were very inconsistent in appearance.
A few looked pretty normal, but a few were really covered in black deposits of unburnt fuel?
Does this suggest possibly the injectors?

Anyway, thanks for the replies!
