Help i have pretty standard r32 gtst, it was auto and changed it to auto, and put a blitz pod filter on, otherwise standard.

THE PROBLEM:

it stalls when slowing down or stoping like at traffic lights or somtimes just gets a really low idile and you have to rev it to get it right again. and when you put your foot down you can feel kind of like hesistation slightly jerky when acclerating, but if accelerate slowly its ok.

WHAT I HAVE TRIED:

i had a bad coil so i got some new ones and they tips all look ok now. stil have 5 spares

got 6x new iridium spark plugs

Ran injector cleaner though it and a full tank of 98 gas

took the afm out and cleaned it with electrical contact cleaner.

im running out of ideas?

any other sensors, or boost leaks or somthing??

please give me some ideas

thanks!!!

sorry i mean i changed from auto to MANUAL, why werent plugs a good idea?

i did a ful service on it because i brought the car off an old guy that had owned it for the last 11 years, did cambelt, oil+filter,plugs, fuel filter, saw one of the coils was prety stuffed so changed it. i got the coils on a dollar reserve auction and scored the whole set for 2 buks. so they are 2nd hand but good but rest of mine look fine

I will check Vac line/hose is split today

does your fuel pump cut out? if it does, do the earthing mod, mine used to do it, then i earthed it out permanently (so it runs all the time) and never had the problem again. Skylines have a circuit that reduces voltage to the fuel pump to decrease fuel pump noise at low speed/idle and being the age of the vehicles this system fails, so just as easy to earth the pump so it runs all the time.

I am sure if you search it you will find an article.

Cheers

cleaned the aac valve it was prety dirty and i thought it worked but then it started doing it. i have just screwed it back anti clockwise and got a higher idle now so il see how that goes. il also try resetting ecu and doing fuel pump mod. hopfully somthing works!!

thanks for all your suggestions guys

my gts-t is exactly the same mate!

i managed to fix the rough idle problem, but i still get a jerk under hard acceleration, or my car just feels like it loses power about low-mid boost.

would love to sort it out but i'm running out of ideas! :thumbsup:

    • Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.
    • OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.
    • Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
    • The frontend wouldn't go low enough because the coilover was max low and the upper control arm would collapse into itself and potentially bottom out in the strut tower. I made a brace and cut off the kingpin and then moved the upright down 1.25" and welded. i still have to finish but this gives an idea. Now I can have a normal 3.25" of shock travel and things aren't binding. I'm also dropping the lower arm and tie rod 1.25".
