When I Put My Foot Down In 3rd Or 4th

[geraus]

Hey guys, recently just had this issue. The problem is that when i put my foot down in 3rd or 4th or any of the gears well mainly the 3rd or 4th(MANUAL), my rev just goes back a little bit like the car dies out but comes back a second.. Could this be my clutch? it feels like a clutch issue. My current mods to my car atm are a Full 3" exhaust with highflow cat, Bleed valve @ 10-11psi, Apexi Pod,FMIC,walbro fuelpump 255l,splitfire coil packs with plugs BCP6RES 0.8mm. Thanks. I was thinking if it was the clutch?

not your clutch. could you explain the problem a little better?

you put your foot down, and the revs drop down? but only for a second then it takes off like it should?

Clutch would mean the car rev's up more easily/free without actually going any faster.

To me, basically the same as every other thread on the mid RPM 'hole'.

Your running 10-11psi on the stock ECU so its likely to be having a fit and going into R&R mode (which is impecably well documented)

Na its not that, I even when i put it down to 8-9 psi it still does that. Because for the past months ive been driving on 10-11 and it was fine.

when im doing about 70kms on 3rd gear full throttle, the car just splutters or for like half a 2nd then clims up ... usually when you put your foot down it just pulls off... now it does some sort of half a 2nd stutter...

when did you check your plugs last?

[geraus]

i just checked em before. everything is fine, it still goes down like i duno how to explain it, i thnk its the clutch sleeping when i put my foot down......

Sounds like Timing issue, a stuffed clutch will normally slip meaning more revs an no extra speed, hope you find it out soon, try getting re-tuned maybe

Red bull would really wake up a sleeping clutch......

[geraus]

so it could be the timing? Because it was fine just a couple of days ago............could it be the gearbox?

il try and explain it again.... Just say im on 3rd gear and my rev is at about 3-4prm .. If i plant my foot down, my car will stutter for about half a mili second n then just pull a lil.... sometimes it does it and sometimes it doesnt. .. its wierd...

Have you tried the usual?

Cleaned the AFM, checked its actually working all the time

Coil packs are working, with good connection

and so on. with all other sensors

ive got a similar problem. except mine does it in 3rd 4th at about 2-3000rpm. i could notice it more when i got my new turbos put in.

ive been told my car runs lean and the timing retards which causes like a jerking sensation, only for a split second or while im "cruising" and my revs are floating from 2-3000rpm.

correct me if im wrong.

hopes this helps

not a clutch, gearbox or diff issue, its 100% around the engine,

as R31Nismoid has said, check things like spark and timing, AFM, to be honest, could be something to even do with fuel,

say when you put your foot down, it just puts a lot more fuel into the engine then wat its ment to which causes the drop in power because it cant really burn it (splutters), then once thats out of the system 0.5secs or what ever it might be it will burn normal again and you get power back,,

If it was your clutch and you put your foot down, revs will go up, speed will go down becuase your not going anywhere, and normally once it starts burning like that it wont grab at the higher revs,

so take the point of gearbox or clutch completely out,

ohh ok mad mad. Il look it up soon! becuase my cars geting highflowed by hypergear !
