Went on a short trip and my 2003 e85 3.0 died. 58000 miles. Revs bounce from 500 to 1500 but no more with engine management light on etc
After a difficult limp home I found it had thrown up codes p1634 p1638 p1639.
Anyone had similar issues?
I looked on here and other sources and it could be linked to the throttle body or the fly by wire accelerator pedal but also found someone stating that the battery was not giving full charge to the front of the vehicle and replaced the positive cable all the way to the front.
Any help appreciated.
 
First thing you need to do is measure battery volts with engine running at 2000rpm, idle and then after 1hr of engine off. Let us know the results.
 
Thanks for the reply ph001.
I bit the bullet and took it to the garage against my better judgement but it was the throttle body.
Replacement from Euro Car Parts for 175 as on offer and 90 to diagnose and fit from my local garage.
Running again. Phew.
