Strange Behavior

[howardm]

Hi,

Now on my second 3 door Rav, a 2005 petrol 2 litre.

This one acts really strange at times.

The dealer has no interest in finding the fault.

What happens is, say I'm in on a level road and don't need any throttle, at any speed.

After a few seconds foot on accelerator maintaining a constant speed, very light or no throttle.

The engine slows and jerks violently until I give more throttle.

I can't make it do this on demand, it does it when it wants to hence problem with dealer.

Any ideas.?

thanks

Welcome to the club.

Assuming it has the correct Iridium plugs, start by cleaning the mass airflow meter with carburettor cleaner then report back.

Good luck!

20 mile report since cleaning as suggested.

Well, that seems to have done it.!

thanks

Hi

I have the same problem. Dealer says no codes etc and as you said not interested in finding the fault.

Will have to have a go at the airflow. Anyone help on where it is etc

How much is the carb cleaner?

Thanks

Hi,

Yes it's on the back of the Air Filter, If you have a short stubby xhead screwdriver it will come off without disturbing

the Air Filter assy.

I put the thing in a jar of fluid as swished it around a bit, then dried it off with an gentle blast of air.

Good Luck.!

Hi

Managed to remove it with a stubby - before reading the post. The screw head is a lot smaller than you think, almost large jewellers screwdriver size for anyone giving it a go. Mentioned this as you cant see them and have to feel for them.

Waiting for a journey to see if its done the job. Cleaned with carb cleaner - £5 Halfords.

Also, the problem was more prominent with the aircon on for anyone else who may come accross this.
