WHEN I START THE CAR ON A COLD ENGINE THE VEHICLES JERKS IN AND OUT THE GEAR WHEN IN D, SECONDLY WHEN U COME TO A SUDDEN STOP THE VEHICLE JERKS WHEN LIFTING OF PLEASE ADVICE

No it doesn't. Any neutral safety switch is to stop a driver from starting a vehicle while said vehicle is in any gear other than P (park) or N (neutral) so the vehicle doesn't just start moving after startup. This doesn't effect the gears any whatsoever. Early US model vehicles had the neutral safety switch on the steering column and was connected to the shift lever. Late model automatic trans vehicles have this switch mounted directly to the transmission shift rod at the trans and mounted to it.

No idea without a drive ,check the transmission level is correct ,when cold without engine running it should be about half inch above the full mark as a quick guide the correct way is start engine handbrake on and choke wheels then put in reverse and check the level

jerks when?

moving the shift lever. with hand?

moving car. in gear,name the gear, drive, L or reverse?

jerks from, 1 to 2nd gear, 2nd to 3? or ? (or when IT down shifts)

pretend we are blind (we are) and cant drive car,(hopeless) and

tell us exactly what works and dont work driving.

hot /cold engine, fast /slow/ accelerating/ decelerating, up hills and what gears.



if engine is hot, is your idle at 800 RPM parked, in park.

y/s

if not the idle controls are out of control and when you shift to drive

IT will jerk. this is an engine problem.

there are lots of other symptoms.

Here's a link to your code.Here's a video to watch,may similar to your engine.

Get the MAF and Fuel system checked.Low fuel pressure,clogged fuel filter or dirty MAF sensor are basic causes of such problem.Start testing the basics first to confirm these are not the issues causing the vehicle **** issues.---------For more detailed troubleshooting,go through the help links provided below,these are solved solutions with complete troubleshooting.Click the link below:---Jerks and Hesitates During Acceleration? http://technoanswers.blogspot.in/2012/07/2004-dodge-town-country-jerks-and.html-------------1996 Toyota Trecel: Jerks while driving and hard gear shifts? http://whatisbyme.blogspot.in/2012/05/1996-toyota-trecel-jerks-while-driving.html

Are the engine rpms climbing when its jerking forward? seems like it could be a Transmission torque converter problem.

Some modern vehicles when change the shift pattern while the engine is cold, by keeping the vehicle in a lower gear for a higher rpm while the engine is cold, the engine warms up faster, to reduce emissions. (Emissions are higher while the vehicle is cold)

What you may be experiencing is that the shift from first to second occurs at a higher rpm when the engine is cold than when warm. This can lead to an abrupt or hard shift. At higher speeds, the shift between gears either may not be changed, or just does not feel as hard as the 1st to 2nd shift.

If this is the case, then your dealer is telling you the truth and there is nothing he can do.

yeah it could be full of water in the gas you bought. see if you can pull a sample and check. start looking at the filters.

I had that problem with another one of my vehicles. It ended up being the fuel pump. The problem was that I let the fuel level in my vehicle get to low, and that the fuel filter inside the pump had gotten debri from the bottom of the tank stuck in it and it was starving the vehicle for fuel. Eventually my vehicle wouldn't start. I had a tow truck driver tell me what the problem was. He banged the side of the fuel pump real hard and the vehicle started right up. I eventually had to replace the fuel pump.
Hope this helps.
