Noticed over the past few days that the truck acts a bit funny when cranking it occasionally. Doesn't always do it, just at random times.
This morning I went out to crank it before grabbing my stuff and heading to work. Typically, as we all know, the truck will almost immediately crank to the distinctive tune (clack) of cold injectors. However, this morning the truck stumbled for just a split second and then cranked fine, but sounded much quieter than usual. Almost as if it cranked on vegi. Once or twice it's done this at lunch after a few hours of cooling from the morning drive in.
Eventually the injectors got louder and the truck sounded normal. Just the first 15-20 seconds seemed odd.
My first thought is that not all the vegi is getting purged from the system on shutdown. Currently the timer is set to the default of 52 seconds and I use the "stomp the go pedal" method that Clay mentioned. At shutdown, I usually rev the engine to 1200 or so rpms and hold it there for 10-12seconds and then let it shutdown at idle.
I know I can adjust the timer cards for a longer shutdown, but is there anything else I need to consider to try and remedy this occasional problem? Hard starts in winter don't sound like much fun.
Thanks!
