I had my car in for emissions and the owner of the shop (who may or may not actually be a mechanic) said he heard a misfire. The sound he was talking about is a light popping noise at high idle (2500-3000 rpm), similar to the gurgling noise when decelerating. I don't really notice it as much when I'm driving but it's noticeable when I'm standing outside the car.
My buddy who also has the DPI exhaust listened to it and says his makes the same noise. Does anybody else with the Spec exhaust experience this? My car had a leaky injector seal and fouled plug on the #6 cylinder but it still does it after replacing the seal, cleaning up the plug, replacing the o2 sensor, and tightening a bunch of loose nuts on the exhaust manifold.
Is this actually anything to be concerned about or something commonplace with this exhaust setup?
