My car has a bogging problem and wants to stall sometimes or doesnt but wants to. I got my codes read today and I got like 7 or 8 then more added on forget exacltly how many. All the codes that came up have to do with my emissions. I have change out the EGR Valve but not getting any the vacumm effect from the solenoid. While the car was idling I popped the MAF sensor off and on nothing happened. Thats pretty much all I did. My gas mileage is horrible. Anybody know what it is or can help me. Thanks any help would be greatly appreciated... thumb
