I hope someone can help me. Recently, I noticed my car jerking between automatic shifting between 3rd and 4th gear. During this period of jerking, the car can not accelerate. It maintains its current speed despite me pressing on the accelerator. It is only after I let up on the accelerator and try to accelerate again does the car accelerate smoothly as it transitions between 3rd and 4th gear. Sometimes, it takes 3-4 tries and during each of these attempts, the car jerks forward and backward (enough to move the passengers bodies a little), and does not accelerate beyond about 60mph.
On a side note, recently my car failed inspection for emissions. I purchased "Guaranteed to Pass" emissions cleaning fluid from Pep Boys and ran it through my fuel system. This problem started about 4-5 fillups following the use of this fluid. Not sure if the problem is related to the use of the fluid.
ANY HELP WOULD BE GREATLY APPRECIATED!
Thank you in advance,
have the same problem?
