Throttle/Accelerator problem

[James28]

My mate is having a problem with his Clio.
He's having problems with the throttle. He'll be driving along and then all of a sudden the accelerator pedal will stop working, and the car will just sit idling at 500 revs without touching the pedal, and he'll get no response from pushing the pedal, and this sqiggly light comes on the dash (I can't remember what this one means?!):

If he turns on and off the problem is still there, so he has to wait a while before trying again.
Its a Mk2 Ph2 1.2 8v. Would I be right in thinking its possibly the throttle body needs cleaning (I'm no expert!?)

Sounds like the Coil Pack to me mate.

Sounds like the Coil Pack to me mate.

What makes it sound like the coilpack if its disconnecting the pedal from the throttle body?

Seems a strange reaction to a coilpack fault TBH

Fly-By-Wire not cable throttle I assume ?

If so, replace it with a known working one... see if that solves the problem. The actuator/solonoid/electrical gubbins are probably borked.

the ecu cover chaffing on the wiring loom is more probable.

Not on a 8V.

Could be a faulty pedal loom connector. Simple fix: remove connector and crimp wires together.

 

[Dan@SJM]

oops mis read it.

 

[James28]

Cheers people.
Is the accelerator easy to change? Is it a complete unit so just a case of unbolting and unclipping the wires?

 

[Chip-mk1]

Assuming its the same as a 172, its got one multiwire plug on it and 3 10mm bolts, takes about 2 mins tops

order of likelyhood

Throttle body needs cleaning/replacing
Coilpack fault.







(eleventy billion other things)






throttle pedal.



Plug it in, the light is on for a reason, it will tell you a fault code. Guessing will do you as much good as scratching you bum hole and sniffing it

 

[James28]

lool. Okay, cheers!
I can plug in my RStuner to read the code, but the chance of me understanding what the code is actually telling me are quite low tbh lol!
How easy is it to clean the throttle body on mk2 ph2 1.2 8v's?

 

[Dan519]

about as easy as it gets

 

[James28]

ah cool, easy to get to then? Anything I should be aware of?
Can't remember the last time I looked at a 1.2 8v

 

[James28]

Found these two vids:

Will I need to replace the seal thing?

1.2 16v:



1.2 8v:

 

[James28]

Right.

Today whipped the throttle body off, cleaned it with carb cleaner, was nice and shiny.
Felt smoother to drive then about ten mins up the road did it again. Now found out it does still drive, but won't go above like 30mph.

Tried pluggin in my RStuner, thinking you didn't need a license to just read fault codes, but wouldn't let me connect, just kept saying VIN unrecognised.

Next most likely coilpack I guess.
Is the coilpacks on the 1.2 8v with the leads aswell or are they separate pencil coils? I remember on my 1.2 16v they were one unit.
