The manufacture no longer makes ECM (computer) for my 2007 FX35. The dealer confirmed this. It only has 93K miles and is still a very nice car. Without this part the car is useless. What recourse do I have?

A crankshaft position sensor is far more likely than the ECM to cause that symptom.

What’s the mileage on the car? If your spark plugs are overdue, that might have been more likely reason for P0302 than coil-pack, so I’m surprised they simply replaced it, I would rather have it swapped with another cylinder to positively confirm it is indeed a coil-pack, not something else. If so…

Thank you all so much for your some times humorous, but always insightful responses. It gives me hope that the car will eventually be fixed. It has 93,000 miles and is very nice car. Its still at their shop and they’ll sending the ECM out for repair. If that isn’t successful, I plan to have it take…

A bad ECM is also way down on my list of possible failures. Just some food for thought here. The shop replaced one coil. I’m assuming they did not replace the spark plug. IMO, the plug (or plural) should always be replaced as the spark plug can be done in by a failing coil. That is also a vice-ver…

Thanks so much for that sage advice. I intend to look into that recommendation once its up and running again. I’m learning alot from you guys :blush:

No, they didn’t replace the spark plug which now, after your insightful comments seems like it would have been a logical, maybe even critical thing to have done. Considering all the responses I’ve seen so far, you may be on to something with regard as to whether the ECM is actually the problem. One…

I have a pretty lengthy history as a mechanic and in all of my years I’ve only seen 2 bad ECMs, One was an ECM that was very questionable on a Subaru. The other was on a Volvo and believe it or not, it was killed by a bit of orange juice from a Donald Duck can of juice. The ECM was under the passe…
