Hey guys,
I just got my new 5spd 2010 GTS a few weeks ago and I love it, but I'm wondering if this is just a quirk of the Lancer or if something is wrong. When I start the car up after letting it sit for a while, it will sit at idle at 1,500 RPM until it warms. I've read up that most new cars do this by design, so I assume this car is no different.

My real issue is that usually I park my car at the top of a parking garage and I usually like to coast down the ramps in 2nd (lighter on the clutch). I'll typically get up to somewhere around 2,000-2,200 RPM and just let it coast (foot off the gas), but then it does something my old car didn't do. After about a second after I let off the accelerator, the car kind of jerks back as if I hit the brakes and decelerates heavily down to idle (again, ~1,500 RPM). When it reaches idle RPM again, there's an audible click from the engine compartment, the deceleration stops and the car basically rolls like it's in neutral. It does not do this when it idles when it's warm (~800 RPM), so I assume it's related to the cold start. I've driven a stick for 9 years and I'm familiar with how different gears will slow a car at different rates when coasting. This just feels unnatural to me because of how sudden the deceleration is.

Now, a.) is this normal and b.) is there any way to get it to stop doing this? I've basically resorted to coasting down the garage in neutral because this is so annoying.

Thanks for any help!

 

a) Like you said, it's normal and it does it to warm up faster.

b) The car is a little jerky when it's cold, especially if you let off the gas quickly instead of gradually. Plus is a new engine and transmission that is being broken in so give it time.
The best way to solve it, however, is to just allow the car enough time to warm up a little. I usually wait until the idle drops to 1K rpm.

 

might be the egr you hear clicking.

 

I have a 2010 Lancer ES. Mine does the same exact thing. It usually only does it in 1st for mine though usually, sometimes second. Make sure the car is warm or else it will start jerkin just how MasterAK said.

 

The click is most likely the AC, the car will adjust the throttle in the Throttle body according to the ecu demand to meet emissions, sometime the car will slow down in certain gears fast, or sometime it will not slow at all! The 1500 RPM is normal for warm up. The car, unless its a PVEZ or whatever, does not have an egr valve. I would say all is normal and you just have to get used to it.

Also being a new car the EECU is going to take a while to learn your driving habits in order to control throttle and fuel correctly.
