Hi All,
I'm new here and need some help.
I bought a 2005 3rd gen about 8 weeks ago and I love it except for one problem, a really bad idle/vibration through the cabin when cold starting, it improves when the engine is warm but is still noticeable.
It went back to the dealer where I got it and they gave it a full service, new plugs, oils and filters and replaced the transmission oil too after the check vsc and engine management lights came on.
The codes pulled showed a misfire on cylinder 2, the dealer said the service would cure all and sure enough no more vsc lights but the rough idle and vibration are persistent.
Any suggestions? The car has only 78000 miles and I'm pretty certain a Lexus isn't supposed to behave like this.
Many thanks

The Jap spec is also the 3GR-FSE. Only certain parts of Asia and the Middle East are using the 3GR-FE motor.

Have them clean the heads and valves. It should be something along the lines of a Top engine cleaning. What they pretty much do is connect a bottle of solution into the intake and hold the vehicle at high RPM to "burn" the carbon build up on the piston and valves.
