I've been skeptical if there is some vacuum leak since the warm idle still goes up and down about ±50～100.
So I covered the air inlet on the air cleaner housing completely but the engine was still running as if nothing happened. Does this mean there is a huge air leak or is it designed to breath the air from somewhere else???? Thanks in advance (IMG:style_emoticons/default/pray.gif) |

I have been ignoring this issue since the car runs just fine. But the injector flow rate result from the injector cleaning service shows that one injector sprays more than other 3. So that is the reason for this hunting.
And today, I accidentally located 2 hair cracks on the top of the plenum where the 2 holes are seen. So I plugged JB weld in it. I will be happy to open the idle speed screw since it is closed almost to the limit. Thanks for the all advises! |
