LFX THROTTLE RESPONSE
 
First off, i have a manual v6 LFX and only have about 200 miles on her.
I have a very noticable delay in throttle body response from an idle. When i give it gas (from an idle) there is an audible "fwopping" noise (which i assume is the throttle body opening) and almost a second delay before any rpms at all. Now I could assume this could be normal, just slow response but, if i just very quickly tap the throttle and let off, i get the "fwop" noise and a drop in rpm where it sounds like the engine almost dies.
There are no throttle response issues at all over 1000 rpms, in fact it performs extremely well at speed. It's just coming from an idle the delay will almost make you stall trying to pull out in 1st.
I took it to the dealership and got the expected "this is normal, it's just the nature of these cars".
Anyone else notice this at all?

Hrrmmm....well my 2010 LLT doesn't seem to have a bad delay. I can't say that it is instantaneous or anything (off idle), but if I give it a good amount of the go juice it seems to take off quick enough that I don't notice anyting abnormal.

Of course I can't speak of the LFX.

Going to be hard to determine this without you trying another owners V6 or maybe even posting a video.

What do you mean by "fwopping"?? I am really trying to comprehend that term but I jut can't no matter what:laugh:, sorry.

There is a delay and it's normal but when you give gas it should be instantaneous but somewhat lazy due to our computer controlled throttle system. It almost sound like you are saying that when you take off from stand still there's 1 sec delay. I can tell you this much, I have a 2011 and mine does not have 1 sec delay from stand still. Maybe the 2012 throttle control is programmed with more delay or restriction but that would just be my wild guess of the night.

Any other 2012 owners experience anything similar?

Sounds kinda like the 300 i drove. I would hit the peddle and it would be a good 1-2 seconds before it did anything. Kinda made driving it a little harder than it should be.

dymndave 10-22-2011 06:49 PM

OK, "fwop" was probably not a good word to use. It is definitely a mechanical sound that i am hearing, like two pieces of plastic hitting together, and i believe i can hear a rush of air also before it spools up. (LOL, this is how i got fwop)
The noise wouldn't bother me a bit except for this delay as i feel like it is related. Like i said before, this may be normal but i have a 2002 V6 mustang 3.8 that does not have near the delay as the camaro.
I really don't know how else to describe it, but i thought i would give it a shot.

Blade 10-22-2011 07:23 PM

Maybe a messed up throttle body? One of the v8 guys in my club, had a similar issue and he kept hearing some weird clicking sound from his throttle body.

I think GM replaced it.

Ozzie RS 10-23-2011 09:46 PM

I'm assuming you haven't done any mods yet with only 200 miles. Go to another dealer and test drive another Camaro or go to another dealer and let them look at your car. Mine has no delay to speak of but different people interpret things differently. My 2 cents.

PsychoRS 10-25-2011 11:17 AM

Sounds normal to me. Most cars nowadays are drive by wire for the throttle and all drive by wire vehicles have some throttle lag, which is especially noticeable in the lower RPM band.

As suggested, go test drive some others to see if it does the same thing, but chances are it is normal. If it bothers you too bad, I would suggest looking into a SprintBooster or equivalent mod that helps in making the throttle respond better to driver input.

TexasCamaro5 10-25-2011 02:07 PM

There's a Vmax Motorsports CNC ported throttle body out for the LLT motor in the 2010 and 2011 Camaros that killed the dead spot in the 2000 rpm range, so maybe it's a similar issue with the 2012's just in a different spot in the RPM range? Although at that low of an rpm, may just be curable by getting into the drive-by wire throttle control and adjusting it there.

Chevrolet Customer Svc 10-25-2011 02:51 PM

dymndave, have you tried testing other v6 2012 Camaros at all to check them against your vehicle? That would be a good place to start to see if your dealer was correct in their analysis. Let me know how you decide to progress with this. I'd like to help all I can.

By Monday I'll have a new cai and scoop installed and I'll see then how the car feels. We're the lucky guys who get to see how the LFX will respond to upgrades.

I will see if i can go test drive some others to see if it does the same.

Someone else recommended the SprintBooster. Would this mod void warranty or be something the service dept. might have a problem with? Also, do you think a CAI would help this particular problem?

Josh, i assume you haven't noticed this problem at all with yours?

RubyCamaro 10-25-2011 10:44 PM

Sounds like you need a good cold air intake to me. IMHO

PoorMansCamaro 10-25-2011 11:02 PM

actually, i think the ported TB would be better to have first. i noticed more of a reduction in lag with that then i did with the cai.

After tons of research I learned that my huge stock rs wheels tend to cause some minor lag during acceleration. It's minor, light weight tires and a cai are supposed to cure it.

My first mods are gonna be RX catch can and scoop with Cai cai (I have these already and I'm installing soon). Then a catback exhaust and light weight battery. Then spoiler and tires.....It should be a slightly better driving experience when I get it all done. What

c_LoW29 10-26-2011 07:43 AM

fwoppppppppppppppppppppppppppppppppppppppppppppppp classic lol good luck and nice purchase. Totally jealous of your dashboard. :-/

bmwdon 10-26-2011 09:29 AM

damn shame it's not the time it takes for old style turbos to spool up for you, simple fix of replacing with better turbos....but alas....no turbos :(

Ok, what I am talking about is not lag during acceleration, but the lag from the time you put your foot on the pedal to the time the engine does anything at all. And there is a slight hiccup during this pause. I am going to dealership today to test some of the other 2012's to see if they do it also. There will be a CAI in the future, but I want to make sure there are no problems before mods..

my '10 has that also ,I have an A6 hoping my throttle body helps this out. Will know when I get home tommorrow and install it.

IMHO, the SprintBooster or equivalent shouldn't void the warranty as it is considered a bolt-on mod, but it really is up to the discretion of your Dealership's Service Dept. A CAI may help a little bit, but due to the nature of drive-by wire systems the delay will still be there to some extent.

Kewl. Please give an update as I am curious. This might be an easy fix if it works.

will do, i also am running a Injen long tube CAI am really pleased with that purchase as it woke up the V6 and helped with MPG when i'm not on the throttle:yikes:most of all it made the engine sound fantastic but did not help with the dead spot when I punch it.

dymndave 10-26-2011 03:55 PM

I just got back from the dealership where I drove two 2012 manual v6's and they both had the exact same symptoms as my car. I can only assume this is the side effects of the ETC as others have suggested on here. Not happy about this but, I guess I will just have to see what mods (if any) will compensate for this.

Good to know that it's not just your car. Thanks for the update!
