Missing At High Rpm In Second

[Adz2332]

Hi,

I own a GTST series 2 R33 and just about 2 days ago i have noticed that in second my car is missing in the higher RPM range. first, third and forth is fine just second. I had the car tuned up only about 2 months ago.

Any ideas?

Cheers

Anyone? should i ring the place where i got it tuned and see what they say?

Id say its ur spark plug gap.

If ur plugs are at 1.1ml gpa them to 0.8ml and it should be fine.

Can they go out over time? cos it has been running perfect up till 2 days ago?

a number of factors can effect it, bascalyl it isnt getting as stronger spark all the time thats why it misses at high rpm.

If hte plugs are old or u dont know when they wher echanged get soem NGK copepr plugs they are cheap, u can get ones that are already gapped to 0.8 , if u do a search they u can find the part code.

I remember u dont wanna buy the plus with -11 after the number becasue that indicates a 1.1ml gap.

Dodgy/old /cracked coils will also casue a miss fire.

And its normal for it to only do it in one gear? sorry bout all the questions

oi adz, take out ur spark plugs and check them, might be old/dirty or they might be new and ungapped. gap them to 0.8mm and that should do it. if u got cracks in ur coils look in the DIY section for a temporary fix, then save up for splitfires.

curently mine only does it in second after putting in plugs that i have not gapped down. So yes it can do it in certain gears as the load is different depending at what gear u in at WOT

So i guess first thing to do is remove the cover and check the coil packs. then if they look fine remove and check the gap on all the spark plugs? then gap them to 0.8? right???
