jkjfjkjf Posted February 15, 2011 Share Posted February 15, 2011 My 2001 GS300 just started to hesitate when taking off from a start, it is the worst @ 2k rpm the check engine light just came on along with the vsc light it is also happening while at speed but at 2k rpm also.

JD-GS300 Posted January 19, 2014 Share Posted January 19, 2014 Resolution: Replace your air intake resonator (Lexus P/N: 1786046142) - $125.25 Go to : www.oemtoyotascionparts.com Search for "Air Intake for 2003 Lexus GS300 - OEM Toyota parts" This will fix your problem. The problem is due to the resonator has developed cracks near bottom (near the heat shield). It is allowing too much air into the throttle body. Basically, the plastic has detoriated and is allowing too much unmetered air into the system. Quote Link to comment Share on other sites More sharing options...
