I usually let the engine warm up enough that the RPMs drop down. The past couple days I've let it warm up for 30 seconds or so and then drive. Well, when I do that the engine seems to rev higher than it usually does to accelerate at the same rate. In other words, it seems to have a lot less power.
It revs up to about 3500. Normally it goes to about 2200 and shifts. After a minute or so, it's back to normal. The tach goes to 6500 before it redlines.
I figured I should see what the manual says. To my surprise it says do NOT let the engine idle after starting it. That one should drive off immediately after starting the car. The reason for this is it takes a long time for the engine to warm up when idling, and that the engine wear when idling is greater than driving at low RPMs. So it says to drive off, but not rev the engine very high.
Strange.
