Hello,
I was wondering if anyone could advise me on a problem I'm having with my V12 engine.
Lately when the engine gets its to normal temperature and I'm driving in slow traffic it starts to rev inconsistently. It doesn't happen all the time but it has become more frequent. I have also experience it revving erratically when I stop and out the car in park. Again it’s not all the time.
I did buy a new auxiliary air valve recently and it was running great but now this. Any suggestions?
