I have excessive fuel consumption in my 88 EA Falcon S Pac, 3 spd auto.
I have searched the forums, found several topics on high fuel consumption, but none very specific.
I would like to know what are the main, most obvious causes of high fuel consumption with the EA, that I can check for myself without taking it to a garage. I am getting about ----100km/15 litres----, could even be nearer 16, at the most!! And thats on Caltex Vortex Gold. Its mainly town driving, but I have been using as light a foot as possible recently, trying to squeeze out as much as I can.
I found my oxy sensor was buggered, I replaced that. New dizzy cap, checked the leads, they are fine. Fairly new spark plugs, all cleaned and gapped. Air filter is clean. Car temp runs in the first "N" and sometimes "O" of NORMAL. Checked diagnostic mode, no error codes came up. Tyre pressures are fine. Temp sensor checks out fine.
What else could be causing my EA to suck so much juice?? Its costing me a bomb to keep her running!
Any suggestions gladly welcome!
Thanks for the reply blueoval.
How would a buggered fuel filter cause high fuel consumption? Im not being a smart arse or anything, I'm just curious. I'll welcome any suggestions. The fuel filter is an aluminium thing, I cant see in it to see what condition is in.
Also, I have never reset the computer, how do I do that? I dont recall seeing it in the gregorys?
I had a problem with my fuel filter on my EB 5ltr recently and beleive me, when those things go, everything else including fuel consumption goes down the tube!!!
You only need a tiny bit of grit in your fuel to foul up your pump. Be mindful of which fuel your regularly using. I've found some fuel from independant service stations to be cheap but occasionally nasty on your car, because they buy cheap, cheap crappy fuel from taiwan.
No name's mentioned but they're supposedly 'the fresh food people'!
Use premium as often as you can from leading fuel retailers.
To reset your computer, Disconect the battery for 20 mins.
Then after, reconnect it.
Start the car WITHOUT using any throttle.
Let it idle for a couple of minutes.(this lets the CPU to determine the fuel values at idle)
Next, take it for a VERY slow cruise around your area not exceding 80km's. Drive for 10km's very sedately like a grandma would. ( This will let the CPU determine the fuel values at cruising speeds ultimately using minimal fuel at cruising speeds)
After this, take it home let it sit for a while.
You've now reset the fuel values on your computer to accept your driving style!!! DONE
(Remember, the fords CPU is learning computer, it will learn your driving style and technique and adapt fuel mixtures to suit)
Thanks for that! I'll get a new filter and reset the computer on Thursday, I'm workig Tuesday and Wednesday :(
And I'll post back results. SO leaving the battery diconnected for 20 minutes will reset the computer yep?
