If I go to pass someone or just "get on it" hard, sometimes my gas peddle will push back at me. Does anyone know what's going on? Is this common?

 

You have an electronic throttle if your car is a 2005? It's hard to get correct information when you post mystery questions? Please think about how somebody can answer your question with no information about what car it is?? Very difficult!!

I would think that since my screen name is ILuvmy05 STR and that this post is on the S-Type thread, that it would be pretty obvious what type of car I'm talking about.

So I'll catch anyone up to speed who is to slow to understand.

I'm talking about a 2005 Jaguar S-Type R.

I hope that clarifies it!

 

I have never felt that. Used to happen in my 1979 Eagle 4X4 station wagon...it had a vacuum actuated cruise control...

Sounds like a chip needing to be re-flashed.

 

Check the handbook.

 

jagV8- is this the section you're referring to:

Kickdown

Kickdown is operated when the
accelerator pedal is pressed fully down,
beyond the normal operating spring
pressure, to provide maximum engine
performance. Kickdown is used in
circumstances where rapid acceleration
is required, such as when overtaking.
Kickdown causes the transmission to
change down to the lowest gear possible
to achieve maximum acceleration. The
gear engaged depends on the road speed

at the time of kickdown.

 

^No. That simply describes the point at which the transmission will shift down a gear or two in order to improve acceleration.

 

I have had previous cars that physically lift the gas pedal when the traction control kicks in but I haven't noticed it happen in the Jag (maybe I'm just use to it). The traction control does seem overly intrusive and can kick in at just about any speed. I've read the manual pretty thoroughly but don't recall anything that mentions it? Seems like it would be more helpful if others could just say what they know instead of turning it into a guessing game.

 

iluvmy05STR, do this:

while cruising at normal, turn off the DSC and then once that is off, nail it and see if it kicks back at you.

 

phd12volt- I'll have to give it a try and see what happens. I went to pass someone yesterday and I was already going about 70, I pushed the peddle down and the car downshifted, but then the peddle pushed back up towards me. This is the 3rd time its happened.

 

that's what it sounds like to me too but at 70 MPH, I don't know unless the DSC is not working properly.
Nice shot at tbird6 !!

 

OK.... I thought it would be in the handbook. It should be, whatever it is.

Failing that, I was after more information. So many questions are asked with so few details and somehow it's the fault of the people who try to reply. Fixed if no-one replies

Many fairly recent cars had a throttle cable so if TCS or the like took over then that cable could be yanked around. The jag doesn't have that AFAIK. Still, the effect sounds like DSC/TCS and you'd think it would be described in the handbook. Suppose it doesn't actually shove on the pedal, it could still be that there's a bit of actual or near wheel-spin with braking which a driver interprets as pedal movement. Would that be in the handbook? Maybe not. How would an observer decide? Dunno! My best guess would be TCS, though. If it is that, it may be unfixable or there's a problem such as worn tires, suspension, eek so many things. One would be: expecting the car to do the impossible i.e. hitting the pedal too hard lol ("I cannae break the laws of physics." Did I quote OK?)

 

I thought all S-types had throttle by wire. If so, then there's no mechanism for the engine to push back on the gas pedal. I was just out playing in the snow with mine (4.2L non-R) and the DSC was have a sh*t fit trying to spoil my fun. No throttle push back.

 

Yes, drive by wire so as I said it's not that.

 

Check the floor mats.

There is no mysterious gadget to move the pedal. It a swing arm connected to a potentiometer with a return spring. Thats it. So either there is a driver error or your floor mats are getting up and behind the pedal OR the pedal is wearing out and has points of friction in it.

Furthermore, it is not very intelligent to make negative comments about people that are just trying to help. Alot of people on these boards have more than one vehicle and their usernames don't always reflect that.

 

DSC has nothing to do with it, there is no electric motor in the pedal assembly it is a simple potentiometer.

If you don't believe me, put your car in neutral with the engine running and flooring it. It should go up to a certain rpm (3,000 I believe) and stay. you can let off the peddle and you will see that the last 1." or so is just freeplay, doesn't change engine rpm's at all.

 

there is a method to my madness

 

"there is a method to my madness"

There is. It may well be revealing.

 

I think that what is felt is the full throttle detent.... I feel that when I drive mine. The throttle becomes "harder" to push when you floor it. I've noticed this since I do it often....'cause I drive a lowly 3.0. As I've posted before, a V8 car would have suited my driving style better.... I'm waiting for one of the message displays in the car to display "Hey dumb*ss, I'm not a R!".

 

dude you made me spit cofee all over the computer, thanks!!! ROFLMAO
