The 2.4L has distributorless ignition, no mechanical advance what-so-ever. However the ignition should still advance, but it is all computerized and what-not
Sounds more like a fuel problem. Even if the mivec stopped working, the car wouldn't just run right out of power right at 3500RPM. Remember the valves are still opening and closing fine, without mivec's adjustment. Look into the fuel and ignition systems first. An engine at 4000rpm needs a lot more fuel than one at 2000rpm. Ditto with the spark (high revs=the need for a hotter, more powerful spark).

 

Even if the stealership says "it's fine blah blah blah" you'll have it documented that it's had this problem. That is very important in case it happens again, and again, and again.... 2k miles is about the time that mine seemed to have lost a little bit of power too. I wonder if they have a demo mode to sell?!?! Keep us posted on what happens, I'm interested to see if there might be a problem with the system.

 

I have 36,000 miles on mine, and MIVEC works the same as it did the day I drove it off the lot. The only times I notice a loss in power are when my air filter is ready to be replaced, or I'm due for an oil change.

 

That's gotta be the funniest thing i've ever heard... the OZ has electronic timing controlled via the ecu. There are no mechanical springs as in old school distributor systems. In fact there isn't even a distributor on the car. Either the tech was messing with you or he ripped you off for something like a loose wire. Seriously though i'd check into that service as that statement is not true thus far.

 

I'd have it serviced... just to get a report of the problem like amg_dragon said. Also check simple things like filter, oil, etc. You may have just had a spot of bad gas or water in the tank from condensation. How's the weather were you live? If it's been raining a lot check into a that. A loose cap or damaged cap can lead to that.

 

i think it's your maf senser (mass air flow) thats what happens to the engine, shuts down or runs real weak one trip to the dealership and a hook up with the dyno machine will tell all

 

I think my power actually got a little better at these miles (probably about 7000 if we convert).

 

So the 2.0L has no distributor, but it DOES have a central coil and plug wires right?

 

It has two coils and two wires... tecnically it does have 4 plug wire sets if you count the plug boot under the two coils.

It is a distributorless system though with duel coils run on a fuzzy logic system.

 

Good luck getting it straightened out.

 

I've driven it all weekend at it has been fine. No problems at all. I'm going to have them make a note of it and see if it happens again. I will be checking all the wiring also. Thanks for all the help.

 

keep us posted...

 

id put gas in your car haha jk... man too maynnt higns it could be the pictures posted are of cam position sensor and the oil pressure sensor 2 for head

 

CHeck your Coil packs and Get it Documented.. ANd DONT BEAT ON IT.I had this issue with my camaro and it ended up costing me 2k in Repairs and a new car cause I got tired of dealing with it.Just get it checked out and dont spend more than a year dealing with this problem like I did.

 

I've been driving for almost a week with no problems at all. I think It might have been a little fuel starved after killing it. I just need to learn how to drive.
