Upon cold start, vehicle engine ran extremely rough, placed transmission in drive while applying brake, vehicle lunged forward while applying brake with both feet initially had little effect.
This has been happening for several weeks. when driving with my foot on the accelerator and when i take my foot off and start to brake, there is a slight acceleration just as i start applying the brake. it happens quite often and i had gotten used to it but one day when i was a passenger and my wife was driving and noticed it. the next time i drove it, i noticed it. it seems to be doing it most of the time. it may be a precursor to unintended acceleration. *tr
