throttle

I got my new air intake Power agency installed correctly. After 1-2 weeks one day i floored my car on sports mode and it starts jittering with the bov going crazy and car starts jittering. i got a random engine light but once i parked the car and turned it off then on, the light went away. but...

Hi guys im wondering what i can do to improve the lagged throttle response on my Gen2 5.0?

Can someone with a 2012 5.0L please tell me is this is normal throttle response for a 2012 5.0 non RSpec. With the engine warmed up and gear selection in park, punch and release the accelerator and see if the RPMs rise to 4,000 and stay there for 1-2 seconds before dropping back to 600 RPM...

Do all 2012 5.0 Genesis cars experience the delayed acceleration and continued acceleration for two seconds after you remove your foot from the pedal? Does a software update exist that makes the throttle operation more like other vehicles? It is a little hair raising to accelerate out from a...

IGNORE - there is another thread about this issue.

Boring out one's throttle body is an old trick that many hot rod shops can do. A source I have used for my RSpec (now sold) and Jaguar is www.maxbore.com. Boring throttle bodies is all he does, and the turn around is very quick. His work is flawless and gorgeous. What you will gain is better...

Does anyone know where the harness is that should be located right above the accelerator pedal. Apparently it should be a 6-pin connector. Im trying to get a apexi throttle controller similar to the sprint booster. If you have pics or anything this would help greatly ad I have looked and cant...

Coming from a GMC Yukon the Genesis is nicer to drive from a complete stop. In the Yukon which had a V8 and gearing for a truck if you had a heavy foot you'd almost give yourself whiplash from a stop due to the 3.73 rear diff and low end torque. The Genesis has this nice gradual but...

My wife has a 2012 Genesis with around 35K miles. We are having a problem with slow throttle response from a dead stop. Obviously quite scary when trying to enter traffic from a stop. We had the vehicle back to the dealership after we purchased the car and they indicated that this condition is...

I searched for any previous thread on this topic and didn't find one, so my apologies if this is covered territory! Obviously one of the major points of contention with the Genesis 8-speed tranny is the laziness of it, primarily when downshifting under WOT. Unlike many similar cars, there is...

So far I have been enjoying my 2014 Equus but lately the throttle/transmission seems to be very jerky or "jumpy" between the 1000-2000 RPM on slow acceleration. Anyone else been experiencing this?

Has anyone tried this? My car could really use something like this if it works as it says. For $289 I'd like to know that is does before I spend the money...

Does anybody know how the 4.6 compares with the 3.8 in terms of throttle response off the line, as well as acceleration from the 20-25mph range? I've been considering a Genesis purchase for the last month, and finally got around to test driving a couple today. I have to say, I was not that...

I have a 2011 Hyundai Genesis Coupe 2.0 Turbo. The clamp that holds the intake hose to the throttle body doesn’t have a hex head adjustment screw, but rather has a rounded head with a hole in it that looks like it requires a special tool to adjust or remove. How do you properly remove this...

The OEM throttle body bore measures about 80 mm. (my recall) on the 4.6 and 82 mm., actual measurement, on the RSpec. Larger throttle bodies have long been a proven, easy, no downside mod. with General Motors LS series motors. For instance my early Z06 5.7 liter motor had a 78 mm throttle...

Into throttle hard form standing start jumping into moving traffic. Then I must completely lift off accelerator apply brakes but trans feels it is stuck in 2nd/3rd gear??? Common my first exp in the last 12K miles.

Hey just brought my genesis to the dealer on Tuesday of this week, I got an engine light and the car went into to "limp home" mode. After turning it off and starting it back up, the car drove fine but I wanted to get the light reset. Apparently there was an issue with the stock ECU coding that...

This problem occurs at speed (above 50 mph). While trying to maintain speed on a down hill section of the hi-way, I reduce throttle pressure and the car experiences a mild bucking. The problem goes away if the throttle pressure is removed (take foot off gas). This problem occurs in moth...

Coming up to my 72K Service, Hyundai Canada is recommending to do a Throttle Injection cleaning service for $189 + Tax. Does this make sense for this price? Thanks

Last week I took my wife's 2010 4.6 in due to cold start misfiring problem. They did a reflash and I got more than I was expecting. I had noticed slight throttle lag when pressing the gas pedal but never complained about it. There has been a lot of Posting on this. Here is what it says on the...
