Thread: D2 td5 poor start and low power on hills

Also to answer your last question , your air intake temp , this is normal
due to latent heat build up , temps will start to drop after running , driving for a short while.
cheers

To discorevy:
Just changed injector seals and started using the vehicle.
No air in fuel system, no loud noises from the pump. Just thought about the valve as someone suggested.
An update.
Starting seems better most of the days but still not fixed. Some days it starts absolutely fine, the other days it has still weak start.
I have changed MAF, MAP and AAT sensors with known good ones. The other car starts and runs fine with my sensors.
Ordered crankcase breather valve.
Changed auto box filter and oil.
Gear change is smoother a bit. Pull is a bit better in city speeds.
Now it is longer weekend coming and hopefully i can get out to highway to see is there any difference.
What i have noticed is that my disco always wants to change gear before 3000rpm. If i really press the accelerator it goes over 3000 also but not huge difference in pull. Then out of the sudden it goes over 3000 very easily, it feels like engine runs lighter and smoother. This all just for once every now and then. Maybe breather valve? I have had throttle pedal faults logged, can this cause it?
Also fuel economy is not one of the best. The best i have had on highway was 13l/100km. Empty vehicle. From full tank till light on and then refilled and calculated. Reading here you guys get the same or less in city. Tanked up $50 bucks, got half tank, light came on and about 230km.
I am sure it all is linked together.
Kind of disappointed.
I will try to mount low side fuel pressure gauge so i can see it while driving also.
Have a safe Christmas guys!

ermpz , don't know if you are able to get live data while driving but if you can give some figures re ambient temp , air flow , boost at 100 kph flat road no wind steady throttle , we can go from there , as long as you don't have oversize muddies

compare with this for now
ambient air temp 23
air flow 260-275
boost .45-.55
this is with nanocom
re fuel economy you need to brim the tank to be close to accurate............you may know this but just to be sure

cheers

Hi.
Sorry for the delay, crazy times.
I can not check the readings while driving. If anyone near port melbourne and have nanocom please let me know.
I changed breather valve. It does respond sharper and does not have so long flat spot when accelerating from stationary. Did cut the old valve to see what's inside. Membrane and spring were in good condition. It was sticking most probably. I was quite happy with the starting at some point but last two days it has been quite lumpy.
