Hi, new QLD member
Hi Kim....welcome to the Club Good to have you onboard and let us know how you're getting on with the Rav4 -

3MZ-FE Low RPM Hesitation & Rough Idle – Stuck VVT?
The first things I would have mentioned to replace are the air filter as you have been off-roading the vehicle and can clog up badly restricting the intake airflow. The other one would be the engine oil and filter as this can affect VVT units if the oil is not circulating as well as it should. Beyond that, I would look at any hoses (induction, vacuum, turbo, etc) to see if there is any restrictions or splits, perishing, etc and replace if necessary. -

Worth checking the ABS wheel sensors for correct operation first. A scan of the ABS could reveal any codes relating to a wheel sensor which may need replacing -

3MZ-FE Low RPM Hesitation & Rough Idle – Stuck VVT?
Hey everyone, I'm chasing a persistent issue on my 2006 Highlander/Kluger 3.3L 3MZ-FE and need some input. The problem started after pushing it hard in sand (blew a radiator cap, I replaced it)). On a cold start, it drowns and stumbles. When warm, it idles better but has a serious hesitation and gurgles when applying more than 1/3 throttle at low RPM. Above 2-3k RPM, it pulls much better. The higher the RPM, it feels, the more I can push the throttle. The big problem is a cold start and low RPM - I push the throttle and it gurgles badly. Lots of unburned fuel, misfires, and no power. Only when I baby the throttle - It has gotten stuck twice on exiting Parking garages, I need to go up fast so it reaches 3k rpm or it starts rolling back. My mechanic confirmed compression is good (all cylinders >130 psi, no leaks) and the base timing belt is still aligned. He pulled codes pointing to a camshaft timing correlation error on Bank 1 (P0012/P0016) and suspects the Bank 1 VVT gear/actuator is faulty. This is an expensive fix, so I've tried to rule out cheaper items. I did an engine flush, which removed a lot of sludge, and cleaned the OCV filters (they were dirty). The VVT solenoids were bench-tested (at least mechanic said he did it) and clicked OK. The symptoms persist: rough cold idle that smooths out with slight throttle, but severe hesitation/drowning under load at low RPM. Does this sound like a classic "stuck VVT gear" on Bank 1 to those familiar with the 3MZ-FE? I'm trying to decide if it's worth replacing the Bank 1 VVT solenoid or cam position sensor first, just in case. I also considered unplugging the Bank 1 solenoid as a test to see if the behavior changes. Any advice from those who've fought this battle would be really appreciated before I spend big on the gear replacement or just use it as is (I am broke atm). 🙏 Thanks -

ABS brakes on 100 series sahara
My 2003 100 series sahara ABS and traction control lights come on. The brake performance does not alter. Have you any clues that might help save the cost of new ABS unit. -

Have you ever removed the Welsh plugs along the length of the block you will be surprised how much sludge comes out when you start to hose out the bottom of the water jackets once cleaned it will run cooler. Ray. -

Tyre tread damage
When a tyre damaging incident happens, like hitting a pot hole or picking up a nail, the age of the tyre is irrelevant. Or are you suggesting that an older tyre is going to fail just because? I've used that regime for nigh on 60 years and never had a tyre fail, without some external cause. Because front wheel drive cars have all the accelerating and most of the braking force on the front, the tyres do wear much faster on the front, than on the rear, this rotation of tyres gives the best overall milage per tyre.

Tyre tread damage
Hey Tony, Thanks for the reply. I always use cheap import tyres. I've never had this problem with my nissan elgrand e51. I'm due for service soon anyway, will get my mechanic to have a look. Hopefully nothing major. Cheers!- 1

Tyre tread damage
Doesn't matter that you have front wheel drive, always put new tyres on the front. Last thing you want is for a steering tyre to fail, not so bad if a rear tyre fails as you still have steering control
