GT86
 

My GT86 is unfortunately having problems with the idle and engine light on and Drift light on. Sometimes the lights stay on for a couple of days and when these lights are on the Cruise Control does not work. The car idles so badly at times that it stalls. (which happens quite frequently) The dealership didn't know how to rectify this when I took it in, kept it overnight and they were still none the wiser next day but apparently full diagnostic test with Toyota - BUT now they want to keep it for a couple of days and take the engine out. :(

Show them the 80 page thread on the idle issue, and THEN try to have them tell you they don't know what it is....

Show them this, also use the arcticles found in the links to Automotive Magazines/Websites Reporting the Issue.
