hey got a r33 series 2 wen putting my foot down it will misfire and not go anywhere just keep jerking, it will also stall wen going up a hill or stopping, ive done

afm
02 sensor
injectors
fuel pump
fuel filter
plugs
icv
tps
checked coilpacks i dunno if they are ok tho

i dont kno wot to do
pipster11
will be coilpacks

you can use high temp silicone from bunnings ($10 for a bottle/can) and seal them up to stop them arcing out but its only temporary so your best off getting some jjr coilpacs or splitfires if you have the cash

+1

You're using electrical components that are 16yrs old. They were never designed to last that long.

coilpacks are only designed for 80,000km's. Thats when nisssan say replace them in a logbook service...
But mine are going strong at 160,000km. im replacing mine soon.
Josh
+1 for coilpacks plus check ignitor too
fasr32
new coilpacks on there way hopefully fixes it

If it is jerking as it comes onto boost, also check for boost leaks.
fasr32
where do i loook for boost leaks intercooler piping and where else
iamhappy46
Anywhere between the turbo and the throttle body wink.gif

Fuel pump relay possibly, I know thats the same response that happened with my brothers car when his was gone. And similar to my old car when the relay went on it aswell.
fasr32
brand new fuel pump jus put in it tho

Check for boost leaks first before randomly throwing parts at it, they will cause ahesitation,not a miss as iamhappy thinks. They will also cause it to stall while coming to a stop. What have you got the plugs gapped to?
fasr32
plugs are normal .08 or woteva they come as how can i find the leaks is there a easy way plus the intercooler piping joins are a bitch to get to as i gotta take front bar off

I use a boost leak tester, but you can use a cigar(lots of smoke) and run it all around the hoses everywhere. If there is a leak, with the engine at idle it will suck the smoke in.

does it idle fine?
but under load driving when it hits boost cuts out right?

i just had the same issue & my fuel pump was clogged check that mate or coils i got some spare parts here you could swap over to see the issue if ya want...

good luck just pm me if you need anything......

Is it ok if I ask a question here? Yesterday I was test driving a skyline and the car drove perfectly until i hit 4500rpm then it more or less cut out, ran like a dog and wouldnt rev any higher. Any ideas what that might have been?
pipster11
that would be coilpacks probably

a mate of mine had a skyline that did the same thing (cut out at 5g) and not sure why, but it was the boost controller, pulled it out and she ran fine
fasr32
done fuel pump injectors and filter tho

Most boost leaks occur when the hose clamps tension up under boost and allow the silicon or rubber hoses to not seal to the intercooler piping. Under vacuum, the silicon/rubber will happily seal to the piping. Its like a garden hose with a small cut in it, might dribble a little fuel watering the plants but block off the flow at the nozzle and suddenly you have a geyser of water pressurising out wink.gif

I prefer to watch the air flow meter voltage spike and timing drop on a scan tool to confirm though but its a common problem

Less boost means usually means the hose clamps dont strech as per my above reason wink.gif

anyone got a tool to cheack for vacuum/boost leaks ill pay to come out and check piping sms me or pm me

ran same boost with and without the boost controller, yet it had the problem with boost controller and no problem when it was out
fasr32
put new coilpacks in still going to stall wen slowing down at lights etc the sputtering has gone away mostly tho
fasr32
got told could be comprssion i fuking hope not
fasr32
tried another ecu that didnt do anything so i dont know ? fuked turbo? low compression? boost/vacuum leak? thats all i can think of
iamhappy46
Your time looking for boost leaks is a lot cheaper than the other two options. Rule out boost leaks before you go for the expensive options wink.gif
fasr32
anyone kno how to test boost leaks and check compression
Mosquitocoil
What boost you running? Could be boost cut... or coilpacks like everyone else has said.
fasr32
stock boost got brand new coilpacks
iamhappy46
Go through every single hose clamp and tighten them all down again. Check all silicon hoses for damage or splits.
fasr32
i need new clamps mine r shit
