Not convinced the heater is causing your problem, just a likely coincidence. If you can give it a boot on the throttle and it comes good and you have about 100xxx km on the clock then guess what....my first guess is coils. If youre not convinced then put the ecu into diagnostic mode and count the flashes, or pay for a consult to say you have an intermittent ignition problem and be none the wiser.

if you wanna test it.... supa cheap will sell you a tube of heat silicone for like 20 bucks, pull them out and cover each coil pack in it. mine use to heat up and then arc out against the block. if you have the cash buy new ones i guess.

hey wolverine, no disrespect bro but

CRC Urethane Seal Coat Temperature Resistance Should not exceed 100°C

most heat resistant silicones have a HR of around 300°C

Sure a spray might be neater but i dont think itll have half the insulating properties as a decent heat resistant silicone or heat resistant gasket sealer.

the bonus is you wont see it as its under the coil pack cover.

cheers

Yeah did think about that could the afm being shit cause this the cars at 94000 but when i turn the car off and start it again the light goes off and drives fine

i think it was shit fuel haven't had it since i have run 2 full tanks of premium through it but coils are on the list when i do my 100,000 service

AFM? Is more likely to cause poor running and stalling. Can of AFM cleaner from local auto parts shop about 20 bucks, take off AFM and squirt clean.

The light going off when you switch off and back on is normal.

Ttry giving it a big kick in the guts when its missing (in gear up to 5000 rpm or so). Might need 2 or 3 kicks but usually will make it run on 6 again.

Shit fuel? Only ever run 98. My favourite is Vortex from the yellow and red company with the scallop for a logo.

Coils and plugs? Well it's up to you on how deep your pockets are when you do timing belt, water pump, seals / gaskets, fluids at 100xxx km

Looking like an expensive service, add about 750 bucks to your parts budget.

Dont tell me, the problem has gone away cos you switched your heater off??

Ran Super Sparks on a RSV, no dramas.

Other folks will say use the Yellow Jackets. I would say everyone has a preference.

Think there are some new supersparks for sale on here, just make a search in the for sale section.

Same for plugs, you can get a set for cheaper if you want to pull the top off every time you oil change.

Best of luck getting the parts and solving that miss.

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Looking for autoelectrician in Perth who can do the OEM to double din stereo upgrade.

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
