Now granted they are saying that this mostly affects 05 and uop imprezas, which probably don't even use an ecu like ours, but I suspect a similar situation likely with ours. Unless somebody with an afr gauge and a custom intake cares to prove me wrong. |
That is a problem with the four cylinder engines, due to the firing order, that has overlapping intake pulses on each side. The eg33 has alternate firing side to side. My 97 Liberty has three resonate interferance pipes in the air delivery pipe to try to reduce the effect.
Its the same reasion that they have that "blat blat" exhaust sound, like a big twin.
