strange new problem
Recently, basically in the past week or so, my car has developed a new issue. In the morning, after it has been sitting all night, I will start it up. It will start up and idle just fine...weather I let it warm up for a while or just go, it makes no differance. Also, overnight temps do not seem to make too much of a differance.
I will put it in drive, and start to go, and it's like the engine has a slight misfire. sounds and feels rough.
Driving around, the car will "buck" and "jerk" and "shake" and vibrate a bit. It does this weather I am on or off the gas. Also, deceleration is more rapid than it should be, with the associated "jerking"
No codes, no CEL, nothing, guages are all normal.
If I then take the car out mid day, it runs great, evenings, runs fine too. Very strange. Any ideas?
