Ok I have a 98 dodge avenger, 2.5 v6 motor,, this car has a little over 200,000 miles on it but still going... The gas mileage is not very good at all though lately and I want to change the plugs and wires and see if this helps,, can anyone please tell me the easiest way to do this or is it a pain.. The front 3 are right in the open and are easy but how do i do the back 3,, is there a motor mount to undo and then move the motor or do i have to take the top plenim off to get to them and then replace gaskets and all that.. Please anyone with some simple steps or the easiest way to do this,,, I want to do it myself and do it the cheepest possible way,, thank you in advance...

 

Sorry plenum removal is the only way ...
