Electrical fault when i floor it

[coxxy]

Whenever i put my foot down to the floor on the accelerator i get the electrical fault light come up on the dash and car goes in to limp mode. If i turn ignition off then on its fine until i put my foot down again.

Hmmm, I would say your map sensor, but I don't think it would put your car into limp mode.

Is it only when you put your pedal to the metal or when acceleration rather fast as well?

 

[coxxy]

if i accelerate fast im sure its ok. just when i floor it

I could be talking out my ass here but it could be the throttle potentiometer?

Is there a way to test it????

 

[Shervi]

I'd go with the potentiometer as well.

 

[coxxy]

how do i check it thou

 

[Sash]

I think the only way to check it is to change it for a new one or by putting it on the CLIP machine.

well it happend again on the way home from work but this time it threw the engine management light on. Got a code for the throttle position and post cat lambda

Had the same problem, replaced the throttle body and the accelerator pedal. Fault has gone.

Try and get a second hand throttle body and swap it over, hopefully it will cure your issues.
