WA_R32 Posted October 30, 2007 Share Posted October 30, 2007 (edited) I was driving down the mitchell the other night i was doing 100ish and went to pass someone and as i accelerated after about 3 seconds it just stopped accelerating i still had my accelerator pushed down it was as if i had taken my foot off the accelerator could this be fuel cut? any help would be good.

Anakha Posted October 30, 2007 Share Posted October 30, 2007 Did it stop?? Or was it like stop n go with the pedal down? ie seems to be missing? That would be fuel I believe?

GTS-t VSPEC Posted October 30, 2007 Share Posted October 30, 2007 I think we need a better description than that. What rpm were you doing ? Did it go away later when you slowed down, or is it happening all the time now ?

WA_R32 Posted October 31, 2007 Author Share Posted October 31, 2007 sorry guys for the lack of info but its a bit hard to explain, it seems to happen at random intervals and can be in any gear (so far its happened in 1st, 2nd and 5th) and it doesnt matter if the car is hot or cold. i think it happens about 3500-4000 rpm but im not usually looking at my tacho whne it happens ill look next time it does. i dont think its a boost leak but i have a boost leak tester so i will try that on the weekend i was also thinking that i could be my fuel pump. i wouldnt think that i would be coilpacks either cause it seems like the whole engine cuts out (could be all my coilpacks i guess) hope thats enough info.

R DIRTY 3 Posted October 31, 2007 Share Posted October 31, 2007 Coilpacks is generally between 4000-5000rpm. It makes the engine kinda stutter briefly however, quite often you can drive through it.

Adam 33 Posted October 31, 2007 Share Posted October 31, 2007 my guess is coil packs as well, if you back off the accelerator abit then it should reduce the stuttering.

Zell Posted November 3, 2007 Share Posted November 3, 2007 my r32 is doing the same thing just loses power when accalerating then comes back after a few seconds. ive asked around to see if anyone knows what the deal is and they all keep saying it sounds like my afm has died on me. Its the only thing i havent replaced since this problem has arised. Ive checked for boost leak and cant find any, have changed my fuel filter, cleaned the afm out along with my k & n filter. Might have to look into my coilpacks after reading some posts Link to comment https://www.sau.com.au/forums/topic/191438-car-not-accelerating-properly/#findComment-3452577 Share on other sites More sharing options...
WA_R32 Posted November 3, 2007 Author Share Posted November 3, 2007 yeah thanks guys now the big question do i just buy some stock 2nd hand coilpacks and risk the same problem again or should i bite the bullet and go and get some splitfires? also has anyone got or tried the Just Jap coil packs they are only 400 brand new over the splitfires which are 490 brand new what do people think?

R DIRTY 3 Posted November 3, 2007 Share Posted November 3, 2007 If you buy secondhand, whats to say they are not in the same condition....or only last 6 months? Buy new, that way you know they will work 100%. I use Split fire and have no problem. Dont know about the just jap ones..but for a $90 difference, i would go with the Splitfires.

GTR-32U Posted November 3, 2007 Share Posted November 3, 2007 before you spend the money on coil packs make sure it is the coilpacks first... as it sounds more like a blocked fuel filter to me.I had my coil packs go on me and the symptoms were a little different.when mine went it was great until you had been driving for about half hour,then it would start spluttering and misfiring under harse acceleration.It did it less when the weather was hot but missed a lot in cold weather...hope that helps.

Wogan Posted November 4, 2007 Share Posted November 4, 2007 (edited) Sorry to chime in on your thread, but i'm having a somewhat similar problem with my R32. My problem is as follows. After i've been driving conservatively for a while, if i plant it in 1st, 2nd or 3rd, the fast increase in rpm and boost causes my car the pop and spit like crazy at about 4000rpm and will continue to do so untill i stop accellerating / change gear. I'm not sure if it's a fuel or an ignition problem. I installed a fuel mixture display kit from Jaycar to see if it was not igniting (rich) or not getting fuel (lean), but the lights just get disco fever. Running stock fuel pump / injectors.. stock boost.. only thing i've changed recently was installing a fmic, so i'm thinking the increased air flow may be the cause of the issue.. but not sure. any feedback, suggestions or ideas would be grealy appreciated.

WhiteHot_R33 Posted November 5, 2007 Share Posted November 5, 2007 R&R anybody?!!!!! can you list all your mods? you would be better off paying for a diagnostic/dyno run than rushing out to get $500 worth of coil packs. . . In the 2 years Ive had my car, it has: leaned out from a dirty AFM from Hks mushroom(oiled) filter and a weak fuel pump. ping!! Hit R&R on the stock computer from too much boost - feels like the brakes are on, it just slows down, but it goes away. Missed with stock coils at around 4500 rpm (PFC) - like hitting the limiter, it pops and misses etc sound like one of those?
