Ignition Coil Rav4 2006 V6 Limited 4x4

[noresults]

I am going to replace the back three coils in the next day or so getting reading indicating #5 bad. Do I need to buy a new intake manifold gasket? The auto parts store is out but $50.00 seams a little high.

Anyone else have any input on this. Thanks

I reused old ones (rubber O-ring like), but they were in bad shape (flattened). In retrospect, new one would be a better option.

Replaced the back three coils and plugs. Haven't taken it to have the codes read but plan on tomorrow to see if it solved the problem.

Note to others don't believe that you should not change the plugs till 120,000 miles. Mine had 103,000. The gap was a good 1/4 inch.

Are we supposed to believe that 1/4 inch part?

84,000 KM #2 coil went (then replaced it), 86,000 km #4 went then the mechanic suggested I replace them all - so I did. 123,000km #5 is now misfiring. Called Toyota Canada yesterday, rep stated Toyota was unaware of problems with the coils; no TSB or recall had been made. I advised her of my issues and the concerns stated on this website; she stated that Toyota doesn't recognize this website, but said she would make note of my concern. Suggestions of best brand of coil to replace with?

What was the part number when replaced last time?
Possibly old, defective parts were used.

There will be never a recall on this as this is not a safety issue.

Thanks for your response. The part number is not listed on the mechanic's bill. As I said in my original post, all were replaced (I hope not all faulty). I am attempting to find if there were defects to the coil at the time, if the defects have now been rectified (perhaps different manufacturers)

At 104K had a misfire and codes for cylinders 2 & 6. Resetting the codes fixed the misfire and the engine had full power again but I figured it was time to do the front three. (I'd previously done the rear three, and with one bad coil had two of the originals as spares.) This time I bought 3 for $80.70 here: Toyota Camry Highlander Lexus ES350 RX350 Van SUV 3 5L V6 Ignition Coil New | eBay and it only took nine minutes to change all three. Part of the reason was these were exact replacement. I didn't have to swap over any rubber parts from the originals.

Thanks for the info - I too replaced the back three; fronts are still working (not holding my breath!)

Our fifth one failed this week, leaving just #6 as original. The dealer claimed that this was a normal wear and tare item and should be expected. I called Toyota and told them about all the complaints. They said that they haven't had any complaints, and also said the failures should be expected.

So, I'm trying to get some data and get back to them. I've started a discussion here to collect data:

Note that I've added data collected from this thread (including my own) - please feel free to add more!
