ok, one of our headlights only lights up when it feels like it, but if you beep the horn, usually it will come on?

what would cause that?

also, car has 150k with original coil packs, had iridium plugs that have caused no problem for 50k at 200 odd rwkw

car has just started randomly hesitating, usually at cruise, havent seen it do it at high rpm yet

time to start looking for replacement coilpacks? or could it be something else

nothing has changed on car in 20k

i had the same problem with my headlight, mine wouldnt work, then when i slammed the door it would work..

it ended up dieing and not working at all so i went on a hunt to find out why and it wasnt getting any power so instead of stripping the loom really far back i did the dodgey and hooked it up to my parkers... seriously who drives around with only parkers on anyway haha :(

ok, bit more info about the hesitation/dying

cars been at shop for the last two days

of course when its in shop, behaves perfectly, no dramas at all

had diagnostic guy come out and check everything, no faults, coils look ok

mechanic seems to think that afm mite be faulty?

problem has only ever occurred at light load, not on boost

cruising at 110 on highway, and then cruising at 60km/h the other nite

im looking at changing my afm to a bosch z32 anyway, so mite give that a try

fuel pump is a reasonably new walbro, probably 12 months old

havent had any issues with it that i know of since install

i am watching the pfc hc whenever we drive anywhere now to see if something funny happens with the afm reading when this occurs

      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.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
