I wrapped some tape around the primer bulb as I needed to drive tonight and need to ggo to work early tomorrow. It started much better, but with a couple of hiccups just after starting, I’m putting the stutters down to a failing primer, or still some air in the system from the work. Then it ran without misfiring at all which was a nice change.

On to the next problem now which is that it seems to be well down on power in the mid range revs where the turbo would normally kick in. Seemed to be blowing a bit of smoke when it felt under power too. I’m guessing turbo related, not boosting early enough in the rev range so I’ll do some more reading tonight on similar issues and try more repairs soon. At least it is driveable for now though.

At least it's still drivable... I can't remember if 07 is a vacuum or electronic boost actuator, but if it is vacuum controlled it could be the control hoses perishing from old age.

Hopefully you get it sorted for good...

Thanks bods I’ll be checking the vacuum hoses. It is quite possible something was disslodged during the repair work. The hard part (for me at least) will be working out what hoses do what there are so many in there.

i had very similar problems, and it turned out to be perished boost hoses on the drivers side under the plastic cover!

same symptoms as mine had, did you get around to checking what I suggested at the beginning of your thread?

Strangely, mine also showed some boost, also smoked more, flat acceleration and was noticeably louder through the exhaust, probably because the turbo vanes were open at low revs, hence the slow spooling of the turbo

Boost is back! After reading ericcs thread above I looked in the same loctuon as the photo there and found I’d dislodged a vacuum hose while mucking around with the SCV or fuel primer bulb. Popped it back on and a short test drive brought back the turbo boost smile. Some of the hoses are a bit perished so might need to replace them soon.

Still need to replace the fuel primer as it seems to drain out fuel overnight making it hard to start in the morning. The one I ordered locally turned out to be wrong, so internet delivery pending.

D40 uses about 3m (with a little to spare) of 3mm hose ($15 at Supercheap).

I hope the primer bulb arrives soon. Not fun trying to drive it at the moment. Once going it seems to keep going, but get a red light or stop sign and it’ll idle fine until you go to take off and then cough and splutter and misfire, stall or just not rev until you I get up to speed again.

Any other possible issues I could be looking at. To me it seems to be a fuel problem, like it isn’t getting enough on starting. I’m hoping it’s just the primer bulb allowing air in.
