I have encountered this problem couple months ago. When i try to turn it on after being off for couple days, it stalls on me. The rpm wont go pass 1k. I had to accelerate it pass 1k to warm it up quicker because it would stall if i left it alone. It gets worse when leaving it for more days wothout turning it on. ? It kinda feels like it gets clogged up with something, but dont know what. ?
