    Unless it's Lexus & Toyota dealership like my local one (two separate showrooms side by side, but share the parts counter & workshops too when needed). You're unlikely to get your IS250 serviced at Toyota. Toyota UK never had any cars with this engine etc. IS300h for example is essentially a smaller Camry and RAV4 uses the same engine too, blahblah. Bottom line, they have parts and they're cross-compatible. IS250 was solely a Lexus car built on a Toyota Mark X platform but that's Japanese model only, so again, Toyota UK is highly unlikely to service this particular car because they probably wouldn't have parts.

    Hence they said they dont have the facilties to source 6.5 litres of engine oil and a filter lol

    All MAFS have scrawny pieces of wire gji. I hope you're not belittling Ford. One thing my Focus wipes the floor with the is250 is taking the headlight out. 2 screws and out it pops. No need to faff about undoing the bumper and removing part of the wheel well trim. Sheesh that was a job and a half. 

    Not at all mr vlad. i have owned many a ford. my favourite was a 1600e mk2 cortina

    Hi folks,

    Said I'd make a post here regarding the IS250 MAF sensor. I've owned my 07 IS250 Sport since September last year. I've always found the gear changes quite juttery with lots of rev hang, poor throttle response pulling away, jerky at low speeds in traffic. Read lots of topics from the US mainly on the manual gearbox/drivetrain in these cars and attributed the cars characteristics to the design.

    A few weeks ago I started getting intermittent faults for rich condition on both banks. Did some troubleshooting and seen fuel trims were sky high trying to lean the mix out. Given it was both banks showing rich, it was safe to say it was a calibration issue with the MAF sensor. I've had cars with faulty MAF sensors before but none had such an impact on the cars running after being replaced. Power delivery is much smoother, gear changes are no longer jerky and there's no juttering pulling away or at low speeds.

    Hopefully this may be of some help to someone experiencing similar issues. I had the car on diagnostics before the MAF started giving issues and fuel trims were all perfect and no indicator a faulty sensor at all. I'd say if you're IS250 is decent age like mine with a few miles on it, its definitely worth replacing the MAF. I'd never have even thought about it only for it did eventually fault out.

    Had exactly the same effect when i changed my maf sensor and air filter for a new one. Car seems alot smoother when changing gear and no lag on the throttle.
