Okay so this is what's happening... I've had p0303 for about 4 months now. I've stopped driving the truck and ride with my girlfriend now. The truck has really bad acceleration and sort of makes a ticking noise that gets faster as the rpms increase. I took it for a drive the other day and now it's doing something new. When I get to 30-40 mph the truck will stop and jerk forward stop jerk forward stop and jerk forward about 3 times and then it continues driving. I have changed the spark plugs and coil in number 3. That is all I have done so far. I have some days off here so if anyone out there could help me through this tutorial that would be great!!! It is a 2006 Dodge ram 1500 4.7l v8 with 200k miles on it.
