For the past month, whenever I first start the car and press on the accelerator it barely moves. The accelerator has to be lightly pumped and then it will take off. Once the car has be driven continuously for a couple minutes, without stopping, it drives without problems. This started happening sporadically and has increased to every time the car is cool. There is also a very thick black residue in my tail pipe.
The front oxygen sensor gave a correct reading and according to the book I have, the back does not do much. All other maintenance is up-to-date. However, the mass air flow sensor stalled the car whenever a slight shot of air was blasted to it. Is that normal? I have seen other threads with similar problems, but no solutions. Please anyone who has solved this problem tell how you did it, I am begging!!!!!!
