Happy New Year all!
I have an 06 FX35 well maintained. Around 205,000 km or 130,000 miles. Well maintained in all aspects. I recently had the plugs changed and the fuel system flushed. Everything seemed fine however in the last month the car has been acting weird. Basically I can be driving and the car will lose power, not electrical power but engine power. It will come back as quickly as it goes away. It can happen once a day, 15 times a day or not at all. A few times the engine has completely stalled but starts right backup. I have had it to the shop a few times and they are stumped too, no codes etc and when they drive it they have had no issues. Over the last few days the battery died, so I got a new one. Now it seems to take about 15 seconds of cranking to get the car to start and its a rough idle for the first 10-15 seconds. Fuel pump seems fine as it can be heard every time the key is turned. I will mention that it seems like all this happened with the temperature drop (in Ontario,Canada its coooold)!

Any ideas would be really appreciated. I have the mechanical aptitude of a monkey so any suggestions will be handed to the shop $$:crying:

Thanks!!!

That cold rough idle is normal. I'm in Ottawa and these past few days have been **** on my car...

I would make sure your brake fluid is topped up. If it's low and it sloshes around, the car will cut engine power... I'm guessing that's the likeliest culprit if your FX isn't throwing any codes. Other than that, sounds like a cam sensor, but that will throw a code...

Brake fluid eh? Never heard that one before, I'll check it out! Cam sensor was replaced about a year ago when it had very similar symptoms, but as you said a code showed up!

Although the Fuel system was flushed, it is a possibility one or more fuel injectors or fuel filter could be clogged. A symptom of loss of power as your driving. With the engine running, put a long flat screwdriver to the fuel injectors and listen for constant ticking on all.
