Intermittent misfire after startup
I have a 2007 GS350 which intermittently runs rough with engine misfires after a cold startup. After the cars been sitting for a while then driven, the RPM's will drop from 600 to 500 or so and fluctuate when idling in gear.
I've seen the GS300 has a CSP program for carbon buildup and a piston ring repair. Has anyone had the same issue with a 350?

The air filter is new. I dont think the plugs have been replaced yet. I doubt it would be the plugs though, wouldnt it have a misfire all the time then? This is a pretty intermittent problem.

when I read the title "misfire" I think of the 350 right away. But I see your sn is 430, I want to check it out cause mine is GS430 too. Now I see it is actually 350.
Goodluck buddy.
