Susuki swift gls, kangaroo-ing as you take foot of throttle??HELP :0)?

Question

We thought it had sticky throttle but after lubricating plate and cable it hasnt made any difference.
To start with, when you first get into the car the peddle is stuck, with a little force with your foot it will move.
Traveling along steady in 4th or 5th gear isnt a problem, its when you need to slow down ie taking foot of the throttle a bit it starts jumping kangaroo-ing like when your learning to drive.
it is purely when you use less presure on the throttle and not reving it judders and jumps in any gear.
Any ideas??
Can i sort it at home, i normally give it ago at home first before going to garage.
And yes i can drive its not me...

Answer 1

Gosh...............throw it away and get something decent

Answer 2

check the way the cable is routed ensure it has not got any kinks or very tight curves on its route to the linkage and check it has not come into contact with the exhaust system and maybe the internal nylon sleeve has melted causing the cable to stick if you disconnect the cable and and try pulling it and pushing it by hand you will be able to feel if it sticks a few years ago I had a Capri that had a similar set of problems in the end I went to disconnect the cable at the pedal end and and discovered that the bottom pivot had lost a circlip and the pivot pin had worked its way half way out so found a tiny circlip replaced the pin and circlip a nd hey presto problem sorted bit of a sod to do had to contort myself to get it back in and the clip into the groove but it fixed the problem

Answer 3

Well the most likely suspect is the cable or one of the linkages it moves, or the pivot of the accelerator pedle itself.
Get down in the footwell and follow the pedle linkage to the pivot, lubricate it. Then under the bonnet, follow the cable to the engine and lubricate the linkages at the end of the cable.
If that doesnt do it, the cable may be worn out. in which case get a new cable.
If that doesnt do it, then you will have to disconnect it to find the source of the stickyness.
