[geraus]

Hey guys, This has been happening for a while now... Everytime when i flat foot past 5,6,7rpm my car feels funny like its struggleing or something? ive changed my spark plugs but im not sure wot its gapped to. The current mods i got so far is Pod,Full 3'inch turbo back with high flow cat exhaust system.. and a HKS SSQV.. I rememba when my car was stock and when i flat foot the car would full funny, like its choking or something i duno... has this occured to anyone b4?

Thanks, Geraus.

if its an r33 then yes, its the factory shit tune , pfc or remap or whatever will fix ..

miss firing is most probally the answer.

check sparkies first if tats not the problem then coilpacks...

happen to me tooo...

get ngk iriway7 or iriway8(or equivalant). this sparkies are made for japanese cars like this. do go trying out stupid sparkies like iridium. cause me a headache....

plz don regap ur spark plugs(cheap way to do it)... its an ancient tool tat ppl use 10 or more years ago... who ever ask u to regap doesnt really know wat they are talking about.

i got lectured by a mechanic saying tat everyone is asking him to regap the spark plugs... he say he rather not do my business when u got a proper item design to eliminate the problem.....

getting a plug is not expensive.... $35 each for ngk iriway7 or 8

[robots]

Which crack and leave you with a broken motor )) copper plugs all the way!

Would this be the same solution for the R32 GTS-t with turboback exhaust, aftermarket cat, fmic, pod, stock everything else? I think mine has those iridiums as well, if i go by what the owner said, which so far was all true.

you have no idea what your talking about.

Regapping plugs is neither dodgy or "an ancient tool"

Its a well known fact that many skylines with mods will not run the stock 1.1 plug gap. buying expensive iridums at $35 each will not solve any problems either. Just get some BCPR6E plugs and check the gap is 0.8mm

all plugs should be checked with feeler gauges to see if they are what they are rated at... just cause it says 0.8 or 1.1mm on the box doesnt mean it is;)

+1

Oh and I think that guys mechanic was just trying to sell the rest of a box of iridiums that likely had been lying out back for a while..

Hey, i dont get it? so is it ok to regap or not? because i dont wana BREAK my motor? LOL? ... And what is the correct mm to gap to? 0.8? ot 1.1?

oh and sorry what brand is "BCPR6E " im guessing its NGK? so when i go buy some plugs all i need to give them is that code right.

Thanks so much guys!

Its fine to regap, just make sure you do it properly.

Yep just give them the code for the spart plug and they can give you the right ones. So as an eg: I use NGK 'BCPR6ES' which are factory gapped to 0.8mm.

don't gap iridium plugs.

the tip is very fragile.

Just go to supacheap and buy 6 copper plugs with the code above, with an 0.8mm gap. (they cost about $4.50 each)

while you are there, ask for a feeler tool to gap sparkplugs.

then as said above, check them.

lol i use a small flat head screwdriver which tip is 0.8mm.... since im always gapping plugs for other ppl i use this.. but yeah feeler guages shoudl always ben used to CHECK the gap of your new plugs... 9 times out of 10 the gap is correct but every now and then there is a misgap

apexi power FC ecu, also get your timing checked and if the timing belt hasn't been replaced get that done also . another thing that may help is getting your car put on a dyno for a power run so you can check the air/fuel ratio , just remember your r33 (s2 im guessing) is 10years old now , small things like the fuel pump may be getting tired
