Genchi Genbutsu :

Hi

Genchi Genbutsu :

Thank you for using Just Answer for your needs.

Genchi Genbutsu :

Did this just happen?

Genchi Genbutsu :

Are you with me?

Genchi Genbutsu :

Hello?

JACUSTOMER-g64jr4b5- :

It started about a week ago while I was out of town. My local mechanic told my son that he could still drive it and that it was ignition coils.

Genchi Genbutsu :

Does the Rav4 drive normally? or is there a drive ability concern?

JACUSTOMER-g64jr4b5- :

Seems to drive normally. May be a slight occaisional hesitation when stepping on the gas at low speeds. At higher speeds, there is no noticable problem.

Genchi Genbutsu :

Thanks. Do you remember what codes were stored that caused the check engine light to come on? You mechanic may have listed them on the repair order.

JACUSTOMER-g64jr4b5- :

My son didn't get the repair codes. The mechanic told him there were 12 codes but that replacing all of the coils would probably make them all go away.

Genchi Genbutsu :

This does sound plausible. When was your last tune up with plugs?

JACUSTOMER-g64jr4b5- :

At 50,000 miles. Currently at 86,000. on 2006 Rav4.

Genchi Genbutsu :

Ok, were OEM Toyota plugs used for this tune up? (Denso Brand)

JACUSTOMER-g64jr4b5- :

It was actually done at about 56,000 miles and was done at a Toyota dealer but I don't know the brand for certain.

Genchi Genbutsu :

If it was done at a Toyota Dealer then the correct ones were installed. At this point I would go ahead and get the Rav4 fixed as early as possible.

JACUSTOMER-g64jr4b5- :

We no longer use the Toyota dealer. He's too far away. Do we need to get all the coils replaced?

Genchi Genbutsu :

If that is what the codes indicated, then yes. It looks liek from what you've told me, the plugs are fine and not the cause of this. It may also be a good idea to have a fuel injection cleaning for the injectors if you haven't done this yet. Every 15-30,000 miles is normal for this service.

JACUSTOMER-g64jr4b5- :

I don't know if the injectors were done at the same time. Are they normally done at the standard 50,000 mile service?

Genchi Genbutsu :

Usually at 45,000 but they will at 50k if you missed it at 45k, Genchi

JACUSTOMER-g64jr4b5- :

OK. Any idea what replacing the coils should cost?

Genchi Genbutsu :

Do you have any more questions for me?
