So I just bought my new '06 3500 4x4 Mega Cab and had a few questions about starting it and some starting things that have happened since my 2 days of owning it.
I am wondering why there is no "Wait to Start" light on the dash when I turn the key to the On position? The owners manual says it should come on every time. Do the trucks bought in California not have grid heaters or any type of fuel or air pre-heating starting aids?
Also on starting, the "Check Engine" light comes on in the "On" position (while I am waiting for the "Wait to Start" light which never appears) and stays on until I start the engine. The owners manual says it is part of the ECU's emission's test cycle during start up?? Can someone tell me more... . ?
Another thing I noticed is, the idle will flux around after I take it out of gear. For instance, I can be cruising down the freeway and coming to a stop at an exit and after down shifting from 5th to 4th or 3rd and as I am coming to a complete stop, the idle will bounce slowly from around 500-600rpms to 800-900rpms. Is this something typical you guys have seen on yours??
Sorry if these are obvious questions to you familiar '06 owners, I'm a long time 12v, mechanically fuel injected mind and am very new to the common rail fueled beasts just trying to adapt to electronically controlled fueling and timing. Paid a bunch of money on this rig like the rest of you and want to know what, if any of you had similar issues like I may be having. Other than these weird instances with the new rig, I am absolutely grinin' from ear to ear at every turn of the key.
Thanks, Joe
