AAARRRGGGHHH (Im stressed)

[banana-man666]

Ok so I have an \'88 EGI and on a long motorway run im returning an average of 10 mpg.

I always heard they were bad on fuel but surely there is something seriously wrong here.

Please help, any suggestions welcome

yeah, bud should be about 5 miles per Litre.. or 20+ miles per gallon.

[gsb876]

Book it in for a remap as you might be running very rich hence the over-fueling

[TiddlesRX7]

Yeah mine runs about 27mpg on the motorway at 70mph average speed. Mines a TII don\'t know how different the EGI is.

........... or even worse you might have a fuel leak.

try new plugs and leads first ( cheapest end ) - but that is terrible MPG

the only time i would expect to see that if you was driving at 70mph in 3rd for extented periods

[banana-man666]

I have checked for a fuel leak and come up with nothing.

Plugs are my next choice but there are so many different recommendations Im stuck on which to get

[elford_tim]

Get standard plugs - have a look around this subforum or call the vendor of your choice.

First though, pull the old ones and have a good look at them...

How does it start? does it fire on the button or take some cranking?

Does it Idle ok?

Whilst you have the plugs out, check the leads are in good order.

I\'ll wait for answers to Grizzly\'s questions before I wade in :yes

[banana-man666]

Starting has been getting progressively worse last week or 2 along with it flooding easier.

It has never idled ok since I picked it up just over a month ago.

Im towing it over to my garage today cos it just wont start any more, I shall take a good look at it there

[Brett]

Sounds like you have leaking injectors at the very least.

Out of interest, how easy is it to turn the engine over by hand? If theres little resistance then you may have found your problem

[banana-man666]

I sure hope its not that bad but ill have a good look over things and make sure thats my first check after the plugs brett thanks.

[Brett]

Well new plugs should make a difference - get some premix in there as well.  Make sure you suirt some engine oil in through the plug holes before you replace the plugs - should help you get it going a bit easier.

Is the idle smooth, or does it bounce around?

[banana-man666]

The idle bounces around.

I had a good look at it today and the plugs were worse than I have ever seen, the air filter is black as night and the oil is disgusting.

Ordered all fluids and parts for a thorough service on friday so I hope that sorts my biggest problems out
