Ek4 trouble

[Leej8]

What would be causing it to over fuel really bad consumption

Bad fuel pressure regulator would be my first thought,
Or stuck open injectors?

 

[Leej8]

You could try this to see if your injectors are stuck open

 

[ruprecht]

I have original ones as I bought another set to try with the problem

 

[Leej8]

Well since you have some off the car do that youtube cleaning diy.
And get a fpr

 

[ruprecht]

How much would a new fpr set me back

 

[ruprecht]

Look at this on eBay http://www.ebay.co.uk/itm/291415559510

Would this do you

 

[ruprecht]

Think

 

[Leej8]

Think you need this one , as it has the plate to go into were your old fpr would be.

But I would just go scrapyard and grab one or two ,

I'll just buy a new one as I fed up with used parts but couldn't go genuine as I havnt won the lotto yet lol ask mechanic why it would be over fuelling and he said oxygen sensor I put a brand new one in but it wasn't oem one he said they don't like aftermarket oxygen sensors granted it was only 20quid from euro car parts I have the one I took out I'll try it tomorrow and clean my original injectors and fire them in and see.as I'm getting normal driving around 55miles to 20quid which is about 17odd litres of BP ultimate

 

[Leej8]

That's terrible mpg mate , but he is right about the O2,
You want oem o2 denso ,
Put your old one back on mate, then if it's the same try doing the injectors.

Changed to the oem lamba sensor so I'll see how it goes in the morning. The one I took out was like a black charcoal grey colour take it thats with it over fuelling? Still got an idle issue tho when cars been drove and ya stop it will dip away down start chugging and then pick up again to normal idle at just below 1k. I've give the iacv a real good clean with carb cleaner and the wee white plastic thing inside is moving freely

 

[ruprecht]

I'll clean the other injectors and fire them in if I've still got the fuelling issue

 

[Leej8]

You know after doing some research and sh$t ,
You sure it's not your tps ? As it only happens at
A certain trottle position?
Give this a read , but remember yours is obd2a and the green wire is in the middle.

 

[ruprecht]

It's not throwing up any cel codes

 

[ruprecht]

I'm near sure it's the cable

 

[ruprecht]

Still over fuelling abit so I'll try the injectors at the weekend

 

[ruprecht]

Still over fuelling slightly hesitation is gone bit idle is abit messy I mean it drops away down and then pick up again

 

[Leej8]

Man I feel for ye . This still going on!

 

[ruprecht]

Hesitation no just the idle playing up. I've tried the base idle setup you posted me and can't get it so my friend is getting a timing gun with a function for idle so I'll see what it's at.

 

[ruprecht]

Do these look like the car has been over fuelling
