I've noticed recently, that while I drive on the freeway, my car would slow down for a second before resuming speed. It's not the same as braking but more like something is 'boggin" down the engine. I'm afraid that someday it would slow down for more than 1 second and..... all hell might break loose.

Has anyone experienced anything like this?

 

Yes and my Type S is going in to the shop for this tomorrow!!!!

 

Please post any answers you would get ASAP.

 

Sounds like the infamous EGR valve is on its way out!

 

I have the exact same thing happening to me...probably time to take it to the dealer. Hopefully it's not anything too big...

 

Mine did that a couple of times recently.

 

mine seems to downshift out of nowhere or bog down too , is this EGR valve a warranty item?

 

Downshifting at random times is not related to the EGR valve. A defective EGR valve will cause the engine not to excelerate when you push the gas and the RPMs will not move.

Downshifting randomly is caused by a faulty transmission which should be covered by the extended warranty. Downshifting will cause the RPMs to jump up during normal driving and the car will slow down because the engine will be revving higher than normal.

You might have both issues and are confusing the 2. Bring it in to your dealer and both should be covered under warrranty.

 

Quick question.... When was the last time any of you with this issue changed/cleaned your air filter? Just asking because I used to have this same issue a while back... I changed the filter..... and Wala!!!!! problem solved... Sometimes it's just the simplest things

 

EGR Valve? Can I replace it myself?

My dealership sucks since they'd only fix anything IF i can replicate it at the day I bring it in.

That really sux. You should try a different dealer. Here a pic of the EGR valve:

Here is a DYI on how to clean the EGR passages and your throttle body:

If you see strain on the engine every few mins out of nowhere, it's your a/c compressor cycling. You can really feel it while highway driving up an incline.

 

I get that bogging down feeling too, like the car is about to stall. It usually happens when I'm crusing consistantly at a very low rpm. It started happening after I changed my headers, so I didn't take it to the dealer to get it checked out. I'm just past 50,000 miles, am I not covered anymore?

 

Wow, described my problem exactly. I thought at first it was the tranny took into the dealer since I was 49, 975 on the odo, they of course couldnt replicate the problem but they were nice enough to say what I'm describing sounds like an EGR problem and orderd the part and told me they will call to schedule and appt. when it comes in.

After reading this thread, I think that is what the problem is. I guess I wont know till I get it replaced and find out.
