I hear a lot about the misfire CSP but I haven't seen much about how people's cars have handled and feel since the service??? I'm about to get mine done and I want to know what to expect. Please reply if you have gotten your GS fixed! Thanks!!!!

e/pect great mileage and engine responsivness. I did nit have lots of oil consumption but I'd frequently find exhaust stains on the rear of the car including black exhaust tips. things are much better since the repair.

Just had my 06 GS300 done at Tom Williams Lexus in Birmingham, AL. - noticed immediate improvement in responsiveness and no more large plumes of smoke when accelerating (also had major build up on exhaust). I think you will be pleased and thanks to Lexus for standing behind the product (mine has 135K miles). Good luck.

surprised Lexus is still honoring this even after warranty.

How do you know if you need this done?

That just shows you that they stand behind their product.

2006 gs300 - it's been 6k miles since my misfire CSP was done. Because the cylinder walls were scorched from the fault piston rings, my block was replaced as well.

Responsiveness of engine is noticeably better with a 10-15% increase in gas mileage. I haven't lost one drop of oil since.

There are no smoke marks on the rear bumper from the exhaust either.

One thing I did notice though was that the engine appeared to be louder than before. This could be a combination of just a "tighter" engine with parts still breaking in. Not too noticeable, though.
