F22a has headers and short ram i believe that is all thats done to it but anyways im getting a boggleing at 1500-1800 rpm but it only does it every other time i drive it, i have a CEL code 12, 17, and 41 now i dont think the heater on code 41 would have much effect seeing how i live in 100 degrees florida but ive read a few posts about egr main port plugs(code 12) the book says check hoses, egr valve lift sensor, and the egr valve... Oh ya code 17 is just the speed sensor lol no sspeeding tickets yet but im thinking that it could be the egr lift sensor possibly any thoughts i dont wanna spend money unless i have to simply bc its just the f22

 

To me this is pretty simple - solve the codes and the issue should go away.

12 and 41 are giving you the "boging" issue.

41 will prob turn out to be the O2 is bad and needs replacement. The heater part has NOTHING to due with the outside temps.

12 is something in the lift - don't worry with the ports as an OBD-I system does not measure flow. So I would follow the testing on the solenoid and then the egr.
