Gtr Problem

[R34]

Hi

Anyone able to offer suggestions

My 32 GTR runs well but then gets a case of the stutters so bad it can't even maintain a constant speed as the engine looses power and runs rough.

Happened to me tonight and then I had to stop at a roundabout.

Just managed to get it rolling again with lots of revs and clutch slipping while a line of cars grew behind me.

A kilometre later it started running fine.

I was taking it to a workshop at the time so we put it straight onto the consult and waddy yah know...no errors

Dam it's anoying not knowing what's going

Can anyone help?

Felt like crank angle sensor to me but no faults came up

I'm taking a wild guess here! Could it be that your fuel pump is failing? Not providing enough fuel to the engine.

Hope you're right as I'm getting the fuel pressure checked today

Be nice to find out what it is

I'll suggest AFM

the number of times the words Skyline and missfire or skyline and splutter get posted on here is unbelievable.

it is all too common.

and therefore, there are all too common checks you can do.

coil packs

spark plugs

afm

those 3 are the easiest to check and cheapest to fix.

plugs - cost you $4 each

AFM - can be cleaned using electric contact cleaner and while it's off the car, you can take the top off and re-

solder the contacts in them.

Coil packs - you can do a cheap job and tape them all up with electrical tape.

or, next time it splutters, pull over and unplug coil packs one at a time to see if the splutter gets worse or doesn't change.

if it gets worse, that particular coil pack is working.

if it doesn't change, then that particualr coil pack is faulty.

change just that one.

if you got more cash, get some split fire coils.

fuel pump - possibly an issue. - new BOSCH one couldn't be much more than $300.

fuel filter - should be under $50 for a new one. worth changing.

they are the most LIKELY causes which you can check/fix/replace yourself for not much money.
