Sudden drop in power
I have a 2005 non-turbo w/manual tran. that has had the same problem since I bought it new but no one(the dealership) can come up with an answer.
When the fan for the heater is turned on or when the fan for the radiator comes on there is a noticable drop in power. you can feel it in the car as well as see it on the tach.
They say that no codes come up. and that the rough idle is normal. How can you sell a new car where the rough idle is normal?
I have replaced the plugs and wires
and I have replaced the air filter w/ a K/N with no change.
