Hey there i am new here. Because where i live MINI's are very scarce and no community , i was wondering if you could help me with some question.
So the problem is that sometimes when the RPM drops from like 1300 to 900 (where it stays in neutral) the car trembles a bit, and sometime the RPM tends to fall to 700 RPM and then right back to 900. I suspect the gas pump not getting enough juice for the engine.
The problem happens without the A\C on. I think I exaggerated with 700 RPM but definitely 800 RPM. When A\C is on the RPM varies between 850 and 950.
The idle RPM holds at 900 constant, no problem there. The shiver appears only when i push the throtle a bit (till 1200 RPM and back to 900).Also when i turn A/C on the car shivers kinda bad. Its not a huge problem but is a bit disturbing. Also once a week i give the car 6000 RPM so i don't think its an injector problem. I also think its the O2 senzor, i will take it next week to the dealer to have it checked.Also there is a problem that i think is connected to this tremor, when i make long trips, like 200+ km, if i stop the car and then start it up again it takes 2 seconds to start and not only 1.It start so there is no problem, but the thing is that it does not start at half a key like usual!
I went to Bavaria Motors and had my engine checked twice and they said that it's working flawlessly. No problems, no code, no nothing. This is not a bad issue that I am having because the car works very nice and there are no engine problems, the problem is somehow in my head because I want it to run like it was new
