My factory r32 gtst doesnt have smooth accleration if the car is cold its alot worse it kind of holds back and then goes then holds back and is really jerky and lacks abit of power. I notice it when car is cold or if have foot flat acclerating, i thought maybe the AFM?? but got told you can hardly boost at all when the afm is stuffed 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 checked hoses for leaks or cracks and cant see anything cleaned aac valve reset ECU Any ideas? whats wrong what can i try?

Hey im from chch too and we both got same problem if ya fix yours come fix mine

cleaning that valve and setting idle has worked it deosnt stall anymore.... BUT i stil have the jerky acceleration! foot flat not smooth at all kinda jerky and hesistant. what could this be? i cleaned afm but could it be faulty? any way to check?

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

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

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!!!
