Engine Misses at 1500 RPMs?

cinellipro · 07-15-2013, 05:16 PM

I have a 2009 base 6MT with 20K miles. I recently noticed that the cabin noise from the engine seems a little louder (just slightly louder, but noticeable to me). Also, while in neutral and not moving, when I press on the accelerator to get the revs up and remove my foot from the pedal, the engine misses at exactly 1500 RPMs on the way down to idle. I accelerate to about 4-5K, and when the RPMs begin to drop the engine consistently misses at 1500RPM. The car is still warrantied.
Any ideas?
Thanks in advance.

Picked up car from dealer earlier. They replaced one of the radiator fans and reset the ECU. The technician tells me the 1500rpm blip is normal. I cannot verify it, but all seems to be working fine.

I notice a pause around 1500 rpm as the engine is winding down from a rev. Is that what you're talking about? If so, I believe it's normal.

It has been mentioned that RPMs briefly holding or dropping slow is normal behavior. IIRC, it's for emissions.
