I've been struggling to set the idle on my stock 2.0 DJet with no success.
With the idle fuel mixture set to max, the idle screw on the throttle body turned all the way in and the engine warm, it idles at about 1500. If I reduce the idle fuel mixture to get the idle down to 900, the idle becomes unstable, seeking between very low RPMs and 900. Everything is stock and otherwise runs absolutely great. I've check for the obvious vacuum leaks, plugging every vacuum line except MPS with no effect. This should have eliminated the lines, aux air valve and decel valve. Everything is adjusted to stock: Valves - .006 and .008 Fuel pressure - 29psi Timing - 27 degrees TPS set properly and circuit board looks to be in good shape Any thoughts are appreciated! |
