Throttle sticking on V6 24V

[Blom]

Hi José

I have a Grand Espace 3.0 V6 24V with a sluggish speeder cable, What did the workshop do to your car with the mentioned problem you described as..

Check stiffness in accelarator pedal: done!. Now it is smooth

My workshop has changed the speeder cable but with absolutely no result, and now the are talking about a sticky throttle valve. Could that be the solution here?

Ive read Anders post about the sticky speeder cable, and ive allso tried what he suggested, but for me with no positive result.

Give a hint back here, thanks :-)

Thanks

I don't think it's the throttle valve, Blom... that would be very unlikely as these things are really simple devices. Besides, it's easily checked by removing the cable and moving the valve. It is one of the few things in this engine that is easily accessible

But more realistically, it may be the cruise control that's causing the stickyness. It is vacuum driven and connected to the valve with a rod. This is also easily accessible and can be disconnected by taking the rod off the throttle drive. If you strip it up against something and switch off the cruise control you should evel be able to drive the car with this and see if that's your problem.

I have cured most of the stickyness on our 24V by rerouting the cable over the air inlet instead of through it. But it's still a bit sticky. I would have thought it was the cable, but given your experiences, that may not be the case with our car either. I'm stll interested in locating the problem.

Hi Anders

Thanks for your reply. Well ill have the workshop look at the problem and tell them about the cruise control issue aswell. Ive allso tried to fix the stickyness taking the cable above the airinlet, but with no better result.

Hope to have it fixed, its impossible to drive with the current stickyness, its jamming all the time.

Perhaps anyone else having some suggestions aswell? What solved José problem with the stickyness in his gas pedal?

By the way, its allso sticky when the engine is turned off, its like its moving in steps.

Thanks

If it's really jamming, then I think you should look at the cruise control! I have experienced a bit of jamming on our car, but only when I have just used the cruise control. Releasing the throttle pedal slightly cures the jam, and then the pedal moves freely again. I think it's the cruise control where a vacuum valve gets stuck or something. While the actuator pulling the throttle itself is easily accessible, the rest of the system is buried below the engine, so I have learnt to live with this small problem. For you, however, it sounds like it's more of a problem.

Where in the world do you live?

PS: I'm splitting the topic now.

Hi Anders 

Im from Danmark like you, we talked about the "tandrem" through email some weeks ago.

Cheers, and thanks for your suggestions, but im still interested in finding out what solved José problems with his sticky pedal.

Oh it's you

  yeah, its me...

well, really nice forum you got here, glad that i found it, lots of usefull info and great help/support.

Btw...

As of today the speeder cable is going 98% better, the workshop sprayed alot of non acid oil in the cable and worked it afterwards, that and then placing the cable above the airinlet worked. Its satisfying that its working, but offcourse it would have made the day if it were 100% working without the slightes bit of resistance.

jfyi

Well, sorry, I know I am a bit late but, as far as I know, they just CLEANED and LUBRICATED the throttle mechanism. Now it is perfectly smooth

In my case, I checked previously disconnecting the rod from the cruise control and it didn't make a difference. But, of course, any stiffness there would cause problems in the throttle.

Best regards,

JOSE

Hi José

I didnt expect you to replying instantly, but glad for your answer, the solution is almost the same as it were for my cable, lots of non acid oil. They allso cleaned the throttle valve, but the thing that solved it were the cable beeing worked at.

cheers...
