I have a 96 Grand Caravan LE with a 3.3L motor it's running very rough or carboned up put put & not wanting to idle. I checked for codes using the check engine light and got these number can someone point me to the problem. I did find a broken vaccum line which I replaced but still running bad. code read 4 3- 2 7 -2 7 Note: I pulled the first 3 spark plugs and they look fine.

The numbers you give only translate as a problem with one of the coils (43), or as a problem with the Injectors (27).

You need to get the full OBD 'P' code read with a scanner.
This will give codes like P0351 to PO356 - which indicates a problem on a specific coil, and codes P0201 to P0206 which specifies which one of the Injector Control Circuits has a problem.
