My engine service light stays on steady and TC comes on sporadically. Code reads misfire #5 & 6 and right rear wheel speed sensor and a couple others I can't remember. Cleared the codes after installing new OEM plugs and swapped coil packs around and still comes back as misfire 5&6. Has anyone experienced this and what was the cause?

 

What are the specific codes that you are getting? They start with the letter P and have four numbers like P1234.

 

All other codes that was clear didn't come back except misfire 5 and 6 ? Check the injectors 5-6 ?

 

I am finding that to be one of the more common causes when i research other forums and on line mechanics advice. I will do that and get back to you when I have an answer.
Thanks

 

I don't have the code numbers. Didn't get them from my mechanic. I will see if he wrote them down and get back to you.
Thanks

 

Had he injectors flushed and seemed to take care of the problem until this past July. Problem started again. This time around we changed out the charcoal canister. Was plugged and screwing up the injectors again. Told to avoid no name gas bars. Today, engine running rough, check engine lite on again. Spent a week in the US and car ran fantastic on Sunoco. Smooth, great mileage etc. 2 tanks of Ontario gas and back to running crap. Thinking of changing 2 or all injectors.

 

IMHO, I find it strange the injectors are the cause.

I'd get the codes - most parts stores in the US will do this for free.

From there I'd still think about cleaning the egr passage in the intake before going for injectors.....or better yet, move the injectors and see if the code follows the move. New seals for all injectors moved of course.

 

what is the temperature outside when this happens?

i would try adjusting the valves...

 

Sorry for not giving follow up. Final verdict was that I replaced injector 5 and 6 with new honda parts. Have stuck to higer end gas suppliers (shell, petro Can, esso etc and have not had any further issues. Guess I had some bad injectors from the start.
