Found out its to do with the EGR valve. But where is it on the mk1

[BrianH]

haynes manual says the following steps to remove it so following the first two should allow you to see it

1)pull out the battery compartment upper cover (i'd assume it means the bit that goes above the expansion tank)

2) remove the bulkhead cover

3) unscrew egr supply pipe union and disconnect pipe

4) slacken and remove two bolts securing the valve, disconnect vaccum hose. also has a note about replacing the egr valve to manfold pipe whenever it is removed.

 

So following the first two should allow you to see it. Any other errors coming up?

Might be worth looking at  http://www.fordgalaxy.org.uk/ford/index.php?/topic/16183-need-help-with-galaxy-loss-of-power/ if you haven't already.

Does that mean I have to remove the battery? Are there any pics Brian?

I'm gonna sound stupid, but what is the bulkhead?

 

Sounds complicated

Bulkhead is the black panel at the back of the engine that gets in the way of most things you want to do. sits under the bonnet/wipers and covers most of the front width of the car. You need to take out 3 bolts to remove it (it then pulls out). If your still not sure which part it is have a look for scuttle drains post in the faq section.

Don't need to remove the battery just the large bit of black plastic behind the battery (not bolted in place just slotted on). only think it says to remove that to allow removing the bulkhead panel.

 

if i get chance I'll find a pic for you and post it.

Is the thing that hides the spark plugs?

Ahhh it's the bit that u can rest tools on lol

Good to see you found it. The bit that hides the spark plugs is the fuel injector casing, Don't think you need to remove that though. Hopefully you can now see the EGR and find something wrong to correct.

I'm going to be removing it on Saturday and cleaning it, got a set of wire brushes and cleaner. So going to be doing that and changing the maf at the same time. Thanks brian

I've changed the MAF, but I can't find the EGR. Is it at the back of the engine bay on the 'wall' with 2 bolts and 2 rubber pipes? That's all I can see that resembles an EGR. Please help.

Would have to have a look in mine to tell you for sure, and theres currently too much snow here to do so today. if it clears up tomorrow I'll have a look. if it helps it will somehow link between the exhaust manifold and inlet system.

Thanks Brian! :)))
