coilpacks: yellow jackets

new sparks NGK BCPR6ES 1ml gap

2000gtt manual, pod, exhaust.

The car was missfiring, so i changed the above items, and now it runs smooth, now i turn the car on and the engine light displays straight away, followed by the other 2 lights, yet it runs smooth and doesnt appear to be missfiring, any ideas? ive tryed taking the battery off for an hour to reset the ecu...

I did the paper clip diagnostic on the engine error codes...It came up with;

21 . Ignition signal circuit• No consecutive ignition signal while the engine is running.

Does anyone know what would cause this?? any ideas??

Are you running a stock ECU? Some aftermarket units/piggy back ECU will sometimes have he engine light constantly on.

I guess first thing I'd do is ensure that the connectors are clean and firmly in place between the coil pack and the wiring loom. Plug and unplug the connector 2 to 3 times to "clean" the connection - sometimes there could be some sort of oxidation.

Ensure coil packs are firmly screwed in place - but do not over tighten as you can damage the coils.

Ensure your spark plaugs are platinum or iridium - easier to fire as opposed to copper - if you are running copper plugs re-gap them to 0.9mm.

Hope that helps.

Failing that you could have got a set of dodgy coilpacks.

Not recommended - as the electronics would have different ratings - something may get destroyed. However if its strictly short term/emergency and you don't rev the car too hard - I cannot see any harm - I suppose its better to drive with different coils, than driving around with a mis-firing car... but that's just my theory anyways :banana:

    • 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.
    • 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?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
