Hi

This car came to me with a few issues...
The idling was really rough, and sometimes would stall, also was no response at all from the accelerator pedal...
On the ecu, faults for the accelerator pedal, a throttle body and some others...
But, was this components at fault?
Follow me on this video to find out what was the problem and how I resolved it...

NOTE: The car was later road tested, and I can happily add that the car drove absolutely fault free... nearly...
It came up with two faults, one for fuel pump, and one for mixture or something along those lines...
They clear, but come back when driving, still, even with this faults, the car drives perfectly... so should be something simple... I hope!
In an attempt to fix the original problem, someone replaced the fuel pump with a third party one, and apparently the fuel rail...
This faults only come up when you drive the car, and I am not sure under which circumstances, as was not me that road tested the car...
I don't believe this issues are related to the repair performed on this video, but who knows... It should be me that is going to have a look at the issue, if I do, I will obviously record it, so stay tuned!
