So Iv had a new fire for about 6 moths and ever since I got it it has had stalling problems. Usually at highway speeds 110-120 km/h my car will stall. Usually when it's halfway between half and quarter tank. I thought it was sending unit at first because it will start after I fill it up. I realized it will still stall after I filled my tank up when it's almost full it will still stall. Sometime it will start right back up sometime it won't unless I put more gas in it. It seams to do it less when I run hi test gas. Iv used injector cleaner a few times and I drive the piss out of my car daily so I'm sure tr injectors are pretty good, I was thinkin their was crud in the bottom of my tank but then why who'll it stall when I have almost a full tank? When it won't start back up it sounds like it wants too and sometimes it'll catch for a sec but then die again. Anyone had this problem before? Maybe faulty ignition coils? Iv drivin this car everyday and it's maybe done it a dozen times in the past 6 months
