It is almost like sputtering while I'm at a light and also driving down the road. It happens until the car is warmed up. Until then, it is an adventure to get down the road. The rpms bounce around until the car warms up.MrSo0h0o said:i think this is all pretty normal for a 13yr old car.. hesitation how? like it isnt pushing hard? most likely b/c it isnt warmed up yet.. for the lunging forward, its probably your engine mounts(dogbone, front, tranny, etc) what do you idle at when u first start the car? upwards of 2k i would imagine.. that would be the reason for your lunging.
