Hey all, a few issues with my 02 Xterra that may or may not be linked.
First, the first time I try to start it (either in the morning or after several hours of non-use) it starts without issue, but then if I park and come back to it, it will often sputter a couple times as I turn the key before it starts. It seems to get worse the more frequently it's used or started, and sometimes I'll have to either turn the key a few times or just hold the key in the starting position as it attempts to start.
Second, when driving on the highway, it's fine initially - I can get up to 70 or even higher mph without issue. If I'm driving for a while at high speed and then decelerate to below 60 mph, the car has a noticeably hard time getting back above 60. The car will start shuddering and try to top out at 55-60. If I keep the pedal down as it goes through this process, it will generally "push through" after a little bit, speed up above 60, and at least mostly stop shuddering.
Finally, this just started happening today (and is the most concerning): it has stalled twice when coming to a stop after being driven on the highway for a few minutes. Once at a red light and once as I was turning into a parking deck - the engine just stopped and I had to turn the car completely off. When I tried to start it again, it went through the same starting issue described above but did start.
Thoughts?
