Flex Plate Issue

Hello everyone. I've been at this car for 2 weeks trying to figure out a solution. After spending several hours researching this on the web, I have turned to you all for help. I bought a 2002 2.7 intrepid. After replacing cam and crank sensors, I am still getting camshaft sensor p0344 light and yesterday dealership checked everything, sensor, wires, etc. and came to the conclusion that the transmission has likely been replaced and the flex plate is not the right one for this car which is why I have hard starts and the computer thinks the sensor is bad.

Do I replace the computer, cam sprocket or the flexplate? And how do I find out which flexplate to get? Has anyone encountered this issue before? Any thoughts and suggestions are appreciated.
Symptoms are hard starts (takes few tries but the car does start) when I step on the gas while driving, car shakes really bad and feels like its going to fall apart. Cruises fine, just can't press on the gas quickly. Seen many people have this issue but their problem was resolved by replacing the camshaft sensor.
If I don't figure this out soon, I have to sell the car so I can get something I can drive to work. If anyone is interested in buying and know how to fix this problem, let me know.

I think they're saying that the flex plate from an earlier year was used - they changed the design, and they are not interchanegable.

Dan's the man on this - he can tell you what you need to do (the correct flex plate).

I've attached pictures of the two different flexplates.
One way to confirm which one you have is to disconnect the battery and remove the crank sensor and insert a finger in the hole just touching the flexplate. Then have someone slowly turn the engine manually via the damper or crank bolt.
If you discern more holes than metal then you have a flexplate for a 2002 & up.

Main crank bolt at front of engine - the pulley at the bottom of the engine.

Oops. I forgot to mention to be sure to back your finger out when the engine is being turned over manually.
Note: The flexplate is considered part of the engine and would not normally be changed on a transmission swap.

So if the plate has not been changed but transmission has and is from older intrepid, which plate should I install than? The one for 2002 or the one from which the transmission came from? Obiously if it wasnt swapped than I still have the original flexplate. Looking at the engine, I'm starting to think the engine was replaced because all the wires are not tucked neatly like they are on original motor. Most of the tabs which hold the wires have either been cut or broken. If thats the case, would the flexplate be in conflict with the computer?

If the motor was swapped with the wrong year, and the conversions were not done then yes, the wrong flexplate would have been installed and you'd need to change the plate - I'd change the flexplate from under the car by removing the transmissions, personally - but pulling the motor to change them is possible too.

Thanks. I'll check to see which plate I have and then go from there.

Has this car ever run right since you bought it? I assume you got it used. If it's unknown whether the engine installed now is original then it may have an earlier year engine and both the Cam sprocket and Flexplate will be the wrong ones if they weren't changed out with the engine swap. Are you in contact with the previous owner to ask about the engine and if it has been swapped?

The first digit of the engine identification number will give you a clue. i.e. it will be '2' for a 2002 engine - '1' for a 2001 engine.
The engine identification number is just below the rear of the left (drivers side) cylinder head. The cowl and cowl support will need to be removed to have any change of seeing it. Still very difficult I use a flashlight a mirror. The last seven digits of the VIN the engine was originally installed in is also stamped in the same place.

pulling either the motor or transmission is a pain in the ash
