Hey all, 91 GLI 2.0l 16v, GIAC chip'd.
Started the car friday, only to see it begin idling around 1100...hum, thats a new quirk! Normally spot on at 1000.
After driving about 15 miles, stopped, restarted, still idling around 1100, but then began to hunt for an idle position between 1000 and 1200. Hasn't done the hunt thing again, just that once, but idle is still high.
Following Bentley, read DIAG code 4431(Idle Air Stabilizer valve faulty), second code 1111(replace ECU...ugh!). Checked continuity across the terminals of the valve(2 wire version), good....but found only 6v across the wire side of the connector, Bentley says should be 12v(~battery).
What to check next to further diagnos the low voltage? Car's running fine other than the idle. l8r, Greg
