When im revving at around 6700 rpms in 3rd gear it sputters back to 6500 and then throughout the rest of the powerband.. Does anyone know what this may be. i heard it may be the spark plugs but i dont know.

 

That's a tough one. So its only at those rpms?

 

exact rpms is 6700 rpms to 6500 in 3rd gear.. and thats the only gear. unless 4th too lol.. but i havent pushed it that hard.

 

Geez, you've got me stumped. It has to be something with the tranny (3rd gear) otherwise the engine would be doing it in the other gears as well. Does it matter if you're at WOT (accelerating hard) or just holding 6700rpm at a steady speed?

 

hmm.. i havent been able to try it at a stable speed cuz in 3rd gear im at 95 mph lol.. but this guy on the other forum said that his 06AT isnt very smooth in vtec in 3rd gear.. im taking to acura tommarow because today i took it to honda and they had no idea what it was.

 

Is the engine completely warmed up? If not, the fuel cut-off is lower.

 

Yeah it does it always.. no matter what time i do it.. Plus i always warm up my car before i run it hard. Ill take a video tommarow and show you guys what i mean.

 

95 mph at 3rd gear? I don't think you should tell acura that when you visit them...or else they might add a note to your record or something ;-P

 

lol it was at the track =]

 

maybe your synchros are going? cause my buddy's 2nd gear on his prelude slips out sometimes and the rpms bog

 

not a chance ...

 

could be the fuel pump - low pressure or low delivery capacity - only way to
effectively test would be with a pressure gauge on the system while you're
on the track. Maybe the dealer has a static test procedure thaat I don't know
about. Good luck.

 

but wouldn't that be the case in any gear?

 

yeah thats what i thought... im taking a video today i just have to see if my closed road is empty

This is the video of the problem.. 1st run i let off right after it happend 2nd run you can hear it more than see but i pushed it further..

 

Probably.

I'm still thinking it's running lean, but ... that "should" set a CEL.
Another possibility is the Buddy Club Condensor and T1R Groundwires
which I'm not familiar with.

How many miles on the car, and did this happen before the condenser and
groundwires were installed?

 

i never really ran my car before the condensor.. and i have 6000 miles.. heres what ill do ill completely take out the buddy club condensor and ground wires even tho i took out half of them and it didnt do anything.. then ill test it out.

 

Are you using 89, 91 or 93 octane gas?

It can also be the torque convertor locking up, as shown on the dyno charts for an auto TSX on vtec.net.

 

Just chiming in here, I have an 06 5AT and I have never experienced this problem. I have taken it to redline in sport shift mode many times in 1st, 2nd, 3rd, and a few times in 4th. I almost always use 91 octane Sunoco although a few times I have used 93 octane Mobil and 94 Shell.

All gasoline in my area is marked with this gasoline MAY contain up to 10% ethanol... not sure if that only applies to the cheap gas or not.

Hope this gives you some idea.. if you're doing the same things and having this problem I would take it to the dealer.

 

i always use 91...

 

ny, always 93 =]

 

i meant 93 whooops lol

 

I have a similar problem in my 05AT. But mine happens at around 5500 rpms or so. I get to around that range and the RPMs just sit there and won't move past 5500.

 

what gear?

 

That seems like torque converter lockup, but if it's not happening to anyone else, who knows…

 

hmm.. interesting.. well. it only does it WOT.. i checked..
