tbow1975 Posted November 19, 2005 Share Posted November 19, 2005 Anyone had this one? From time to time, after starting the RX motor, it will have a hard time idling for a minute or so. It sort of sputters, until I give it some gas for 30 seconds or so to level it off. Once, it even stalled while sputtering, ignoring me when I pressed the gas pedal. I took it to Lexus, as always, and they told me they replaced a sensor and sent me on my way. Well, it still does this from time to time. I took it back to Lexus and they told me they couldn't reproduce the problem, so they wouldn't know where to start. Any ideas? Thanks!

riwyle Posted November 19, 2005 Share Posted November 19, 2005 Exact symptom I had which I corrected by cleaning the Idle Air Control Valve (IACV). Not difficult to do for someone with a modicum of experience in working on cars. If not, I do not know if Lexus would do this without insisting on replacement. Try to find an independent shop that may be willing at a decent price. What sensor did they replace? If by sensor they meant the IACV, then I guess cleaning would not help. Good Luck Quote Link to comment Share on other sites More sharing options...
SKperformance Posted November 19, 2005 Share Posted November 19, 2005 iacv being clogged is common. It is a valve not a sensor Quote Link to comment Share on other sites More sharing options...
