I recently drove my rescue jag to nashville then union city and back home and I have ran into this issue.

After driving when I hit traffic or a stop coming into town I get restricted performance with codes P0175/6 rich bank 1/2

my first thought was learning but after multiple times it keeps popping up. (5 times so far)
also after a couple more mins of active driving the restricted performance clears and just leaves the MIL on but no longer performance restricted.

Leaking injectors or rinigs or anyone know another place i should start looking?

 

Very dirty air filter; dirty throttle bore; dirty plate; crapped up injectors

 

+1 on Jim's reply. Start with the air filter and work your way to the TB. Take the MAF out and spray it from both ends with MAF cleaner, remove the intake tube from the TB and clean out the crud. If that doesn't fix the issue, check the fuel pressure. I got those codes a few years ago and it was the FPR. Got them again last March and it was a dirty MAF.
