Odd Miss At Idle

just wondering if a stuffed carbon canister can cause a slight miss at idle and the car to run rich.

i have been chasing this problem for a little while, first thinking is was the BOV, i have blocked this off, no change replaced most of my vacume lines and still no change, checked IC piping all is tight and no leaks. thought might be AFM so i have resoldered it and still no change, so i'm wondering if a stuffed purge valve on the carbon canistor could cause this?

mods to the car at the moment

FMIC, pod, no BOV, profec e01.

Im getting a similar problem with mine (weird missfire on idle) and havent been able to solve it yet (its getting less frequent though) have been told that a rorted O2 sensor could cause it so thats my next step, it should arrive by wednesday so will keep you posted.

how did you go with the 02 sensor

i a small air leak, which seems to have fixed up most of the miss however still have a very slight one so interested in how you went

Changed it last night and the car still has a slight misfire (a lot less frequent though, maybe 1 every 20 seconds compared to the 5 every 10 seconds before) but all my other problems are fixed now because the O2 sensor was pretty much dead, was covered in soot and muck and looked like it was the factory one :X

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?
