My first Maserati Qp 2008
I have a 2008 Qp when I start it taps for a second & stop so I thought maybe my timing variators was going bad but it don’t do it every time I start the car. It also ride very rough sometimes as if it has bad gas in & want to cut off. Can someone please tell me what this possibly could be. I took the car to dealer & they said they couldn’t figure out the problem because the car wasn’t making noise at the time & the engine check determined the engine was strong.
