CEL and rough idle

[greasemonkeyjmj]

my wifes 07 pt with n/a 2.4 liter and auto transmission has been running good. she started home and the CEL came on , and car started surging. she pulled over and killed engine. she restarted it and light was still on. she came home and car was idling really rough. she told me about the surging and i said she may have picked up a bit of water in fuel. we decided to go to autozone so they could check CEL. we stopped at gas station to put in gas, and when i restarted car the light was gone. so we didnt get it tested.it stayed off about 3 weeks,until today it come back on.and the engine has seemed to run rough with a idle of about 6 to 7 hundred rpm since the problem started. we went to autozone tonight and they pulled a code P0068. i read all the info i could find here about it. i went out and checked the engine all over and didnt find any vacuum leaks. any idea on what i should try next ? any info will be greatly appreciated.

greasemonkeyjmj, welcome to the Forum!!

If it is a 2007 it should be still under the 36/36 warranty, if so take it to the dealer to be checked out. Good Luck!!!!
