how many miles do you get to a tank of fuel..?
My Z22yh vec estate is drinking fuel like water....
So pretty much all my travel is motorway miles doing 80 miles a day round trip to and from work... since I last filled up I have covered 180 miles and that’s used up 3/4 of a tank of fuel... I don’t hammer it normally stick to 75/80 under 3000 rpm...
last week I had engine management light on which flagged a few codes ...
I changed the Front lambda and the mas air flow on the air intake with new parts .. however the engine light kept coming on...
so I checked the swirl flap and it seem to be a bit stiff but after a bit of gentle persuasion it seem to move back and forth and engine management light went out and has Not come back on since...
but still drinking fuel.. I know swirlflaps can be a problem..
I will change the cts as I know this can have an effect too... I have also noticed my temp gauge only ever goes up to 85 never in the middle at 90... I have a feeling my header tank has a crack so guess I’m loosing pressure there stopping it getting up to the correct temp , and I’ve had to top up the coolant a few times, would the fact it’s not the correct temp have an impact?.. however I don’t seem to be leaking water externally.... I changed both chains a couple of months ago with genuine parts so I know their ok.. and tyre pressures are ok too .
car dose seem a bit sluggish.. not as snappy as it once was it’s covered 12700
Any other things I can look at ... I do have a spare egr valve second hand .. would that make any difference if I swop it over?
Any suggestions would be greatly appreciated ...
