Can one of our teccies explain how this is achieved in practice? My last car had a throttle cable - although newer versions of the same model went over to drive by wire. So it has been around for a long time -
15 years or more.My 'new' car has it - again with Bosch petrol injection - and it seems to have a fault. At low speeds, when pressing the throttle pedal, it can do nothing - but the engine doesn't stall. Just like you'd taken your foot off the pedal. It's at its worst after leaving the car for an hour or so when it was hot before stopping. And seems to be mainly around the closed throttle position. Go for a fast takeoff, and it's OK. But not something you can do in heavy traffic.
It would seem to me like a worn track on a pot.
Hence the question. It is a pot they use as a pedal position sensor? Or some form of solid state rotary position device? How about the engine end? Is it a stepper motor, or a PCM controlled solenoid? Or something else? Not even sure if this car has a throttle body. Or several.
The other things that is confusing me is why it would be worse after the engine 'heat soaks'. As it is a mid engined car - so the actual pedal some way from the engine.
When I first experienced it thought it was a fuel vapour lock. But the perfect idle says otherwise.
The car is going back to the dealer for a warranty fix. But being a curious soul, like to have an idea what the fault might be.
