Hey all,

I recently changed my plugs to NGK Iridium's. I took it for a drive after they were put in and it went fine right thru the rev range.

About 20mins later i took off in 1st, change to second and nothing happened. I would have my foot down but there would be no power.

I take my foot off the gas for a few seconds then i can feel the power come back on and it is all fine again.

Sometimes when i am at idle the revs will rise to 1600rpm and stay there.

When i change into the next gear (usually into 2nd), is when it happens most of the time.. I can drive it on the highway and keep it at 100kmph (aprox 2900rpm)

It Seems like a boost leak, or something to to with the fuel. It was fine before i change the plugs.

All help is appreciated

new insight to my problem

when the car is playing up it wont hit boost.

I revved it to 5000rpm and the boost guage rose in vacume and came to a stop right on "0".

I can feel the car is about to stall so i put my foot on the gas and nothing happens... AT ALL! it just stalls.

If the car is cold it drives fine.

If the engine is warm but the car has been sitting for a while it is fine.

If the car and engine is warm it drives like a dog!

So when something on my car warms up.. it f@#ks up?

it was the plugs people.

NGK Iridium's

I put my old ones back in and it is all good now.. Just miss fires a bit, which is why i bought the Iridium's in the first place.

They came out with a build up of white crap on them? Does that mean im running to rich or lean?

And why would my car act like this with these plugs?

Try plugs at 0.8 and see how they go

can skylines be tuned to run better with better plugs?

I wasted that $120 so i think i will get them when i get my big service.

do you think that they overheated? Cuz they were fine for the first 5min of driving... Do you think that it wouldnt hit boost because the car could sence they were overheated, so it was like a safety thing.?

I agree wholy with WazR32GTsT A set of coppers are just as good the only reason I can see to use Iridiums is the life span, as it is a bitch to take RB spark plugs out and also puts stress on the coil pack connecters as they end up brittle and can break. They wont give you a performance gain. Coming into summer it wont hurt to put 1 heat range colder plugs in.

    • I have seen a case where the starter motor shorting against the casing caused a massive voltage drop + so much EMI that it caused all the sensors to spew garbage data at the ECU. Test the battery to make sure it has acceptable CCA/capacity first, I have gotten "brand new" batteries before that couldn't even power a 10W light bulb without dying probably because it sat in a warehouse too long without being charged. Only easy way to diagnose this 100% is put an oscilloscope on the battery and also look at key sensors to see if there's any clues.
    • There's a bunch of smaller shops that don't quite attract Singer money but are still hiring from that same pool of labor. Those are the body shops that you go to when you can't afford a Singer, but your old Porsche needs some serious bodywork. You can't exactly take those cars to the usual insurance body shops. When I say restomod, I mean they'll do something other than 100% OEM/OEM-equivalent aftermarket parts R&R. In the Porsche world this would be stuff like taking a 50k 964, doing a bunch of deferred maintenance/unwinding the nightmares the previous owners did to the car because a lot of people that own these cars tended to be penny wise, pound foolish types, then maybe some relatively simple off the shelf modifications to things like suspension, transmission, engine, headlights, etc. and you've spent 130k USD. When even the worst houses in the poor neighborhoods are worth 1M USD and the nice houses in wealthy neighborhoods are worth 3-10M USD suddenly 130k spent on a 50k car seems cheap.
    • Hoping to get a few ideas to help troubleshoot this issue, I'll try to keep it short.  A mate popped the motor in his 2018 LDV T60 with the 2.8 turbo diesel motor. He swapped it and I was his phone a friend when he got stuck.  The new motor is in, however it won't fire. The battery is literally brand new, when you crank it the volts very quickly (say 2 seconds of cranking) drop to 8 volts and the engine stops turning over. Watching the belts, I'd say they move about 5cm before coming to a stop. We put a booster pack on, no change.  The only potential issue I'm aware of is, when we pulled the motor the grounding strap was still attached. The strap copped a thrashing before we realised what was going on. It looks okay-ish but it's going to be replaced to rule it out.  The main challenge is, I wasn't there for 90% of the work. This is his first time doing any major work on a car and he was learning as he was going. He thinks everything has been put back together properly, however I'm not entirely confident that this is the case.  It would be good to get some ideas about what else to check. The car isn't spitting any codes so that doesn't help.  I've attached a photo, because why not lol.   
    • I mean an N1 came with a minimal paint thickness compared to dealer models. It’s probably had a ton of vinyls and stuff possible a race paintjob or two over the years. you don’t buy an N1 for its stunning good looks or comfort 🤣 you buy it to send it and measure how much air you can get on the hill at Bathurst
    • Yeah, but "restomod" implies Singer and things like it, which implies drug money / trust fund maturity.
