nka Posted June 21, 2009 Share Posted June 21, 2009 Hello, I've got the "pulsing" throttle problem. After reading "Pulsing Hesitation at Constant Throttle" I've done some datalog with romraider. Look like my front o2 is defective. Could you confirm ? Also, if front o2 under the motor warranty ?07_O2_romraiderlog_20090621_130358-50.csv Link to comment Share on other sites More sharing options...
GTTuner Posted June 21, 2009 Share Posted June 21, 2009 I would need to see a/f correction percentages to be sure but I just had the pulsing hesitation and the front O2 was the culprit. http://legacygt.com/forums/showthread.php?t=114267 Link to comment Share on other sites More sharing options...

It's under motor warranty ? What o2 did you get finally ?07_O2_romraiderlog_20090621_135914.csv07_O2_romraiderlog_20090621_140205.csv Link to comment Share on other sites More sharing options...
nka Posted June 22, 2009 Author Share Posted June 22, 2009 I'm in the wrong section? Link to comment Share on other sites More sharing options...
GTTuner Posted June 23, 2009 Share Posted June 23, 2009 Log this for me; RPM, MAP, A/F# 1 voltage, A/F correction 1, injector pulswidth, mass airflow voltage, total timing, knock correction. Drive and record the surging. The sensor is covered under the 3 year 36,000 mile waranty, no coverage under powertrain (5yr/60). Link to comment Share on other sites More sharing options...
