I have a 1997 200sx SE automatic. For the past couple weeks I noticed an increase in hesitation in my acceleration. Now for the past 5 days it has been really bad. It is to the point where I can put the pedal all the way to the floor and it takes a good 2-4 seconds before it will even accelerate, it will act like it wants to but will take awhile. Unfortunately, I am college in which I have no garage or tools to work on my car. I am going home this weekend. I have searched and I am going to try using a fuel system cleaner to start off with, to see if the injectors are clogged, then I may change the fuel filter. I also think I might try cleaning the throttle body, clean egr valve/tube, and check the vaccuum lines although I am not quite sure on how to do that. Also is there anyway I could check the fuel pump to make sure it is at the right fuel pressure? If you guys have any other ideas why it would be doing this, I would appreciate any input. Thanks in advance.
