Well, let's see, since December 20, 2007, when I bought my Charger R/T. My present car does the same thing.The last 2 times I started my 14' SRT, the RPM took about 60 seconds to get into normal operating idle range (without me giving it gas). After start, idle was approx. 1350 RPM. Aftter a minute, settled to approx. 700-750 RPM
The car has 4750 total miles. It is not due for oil change until 7500 miles. Fluid levels look good. Both start ups were in my garage, on dry days, approx. 80F.
Has anyone experienced this?
