nah with an egr code and ur bouncing idle uve more than likely got vacume issues, check all the hoses around the mapp sensor and that the vacume hose to the egr valve is on there correctly, check for any leaks cracked or damaged lines, also check all the hoses coming off of ur intake manifold, if ur plugs/wires/cap and rotor/ dizzy are all fine u shouldn't have these issues, u can also try using a cleaning solution on ur eavc valve see if that clears up the problem and if it gets down to it decarbonize the engine.
