Car Jerks At Times Plz Help

[RB32]

hey guys,

i have an r32 gts-t and my car seems 2 jerk in 2nd and 3rd when i floor it from 4000rpm onwards.

it feels like the car wants 2 go but sumthing is holding it back. Something must be causing it struggle.

This doesnt happen all the time but does happen

Any help would be appreciated thanx guysss

Too vague, we'd need more info than that, one thing I'm 90% sure of is that its' either fuel, electrical, or mechanically related though......lol.

lol... well when it happens the car doesnt flow smoothly sorta like somethings cutting out therefore it jerks so it could be electrical.

a mate of mine seems to think that it could have something to do with my engine coils, could that be right?

thanx

thanx

Nah, you can buy them in the FS section here. Then you just swap it for one on the motor, and keep swapping it until you find the faulty one.

Takes like 2 minutes to swap a coil once the valley cover is off.

At what revs does it jerk?

hmm sounds good might chek it out thanx

it starts to jerk between 3500 and 5000 after that its usualy finee

[tridentt150v]

If it was a coil and above 3500rpm, I've reckon it would keep missing right through the rev range once it started. Secondary winding [if nissan coils have them, not sure] collapse would be at or over 3500.

Maybe the problem is elsewhere.

fuel pump... high rpm plus surge/cutout.. my moneys on fuel pump

[Cubes]

How much boooooooooooooooost are you running?

Surging... likely to be fuel as others have stated.

[RB32]

hmmm i mite go get it checked out

im running stock boost wif a cat back exhaust so its roughly 8 psi

mite change my fuel pump, that sounds about right

[infected flow]

ok do u have an aftermarket computer...?

has it been tunned...?

if it does have an ecu i would put it down to tune or over fueling...

need more info from you.

cheers

Throw it on a dyno for $30-$60 and give it a quick power run.

You'll then know whats going on; much better than replacing this and replacing that when it may very well be fine.

before u check coils check spark plugs, i thought i had coil problems but the sparkies were screwed. Go buy urself a set of coppers for $30, then if that doesnt fix it, its the coils.

It sounds like a rev limiter at 4000rpm right?

[RB32]

the car is pretty much standard apart from a cat back exhaust, pod a BOV.

standard computer

might change sparkies................

just out of curiosity how much would a bosch fuel pump be and will it change anything performance wise????
