Hi I am new to forum's and have couple of problems with my new purchase if any one can help. It's on a 2006 srt8 one thing is on a rare occasion I coast into slow traffic then go to accelerate out the other side and there's no throttle response a couple of stamps on the pedal and a few seconds later it picks up as normal I will get it read for fault codes soon but has anyone encountered this ? The other is the back door lock it opens with the other doors but when you pull the handle it draws down the lock at the same time and stops it from opending is it a week solenoid? Cheers
