I am having this issue it seems when engine is cold versus hot that I will pull up to stop sign and have soft braking and my engine will all of sudden have a little rpm surge and because i don't have full brake on, it lurches truck forward. I don't seem to notice this when engine is fully warmed up but I am going to start monitoring this closer, but would appreciate if anyone else has experienced this letting me know. I had one experience right outside where I work where i drifted into a stop sign before a three lane street and because I didn't have full brake on, it all of sudden lurched me forward out into the beginning of 1st lane and thx god no one was in that lane or it would of been ugly. That was only time I can remember having a little more speed before I got to stop sign and the lurching was much stronger, normally its a small jump in RPM's that I notice. Appreciate any insight!
