I have a 1999 Toyota Camry (4-cylinder). When I step on the accelerator, it hesitates for a moment before accelerating. Once it finally does kick in, it isn't jerky but fairly smooth, just takes a while before it will go. Other times, when I accelerate, and the car is actually moving, I feel as though the RPMs are higher than they should be considering the (slow) speed that I'm going. These problems have increased quite a bit over the past few weeks. Prior to this, my check engine light came on. An autozone employee checked the code related to the light and said I have a faulty EGR. He didn't seem to know whether or not this would be at all related to my acceleration problem. Someone else suggested that an EGR's importance is more environmental than functional. While I'm all for "being green"...can only afford one problem at a time, and the acceleration problem comes first.
1. Any idea if the two are connected, and if not, what my acceleration problem might be?
2. How critical is a properly working EGR anyhow?
Edited: The actual code according to autozone was EGR P0401
