Ok, my car through a code, the cod # was P1441 which is the EVAP system. It was have poor idle and stall. So i looked in the book and it said it might be caused by a hose. I looked under the hood and saw that there was an elbow piece coming of the bottom of the EVAP purge vacuum switch but no hose. Also there looks like there should be a hose coming off the back of the purge solenoid vavle but i could be wrong. Does any one no what these hoses are called please help.

 

You have to be referring to the 97 in your sig. That hose on the bottom is a vent hose and does not connect to anything.

You should have a hose coming from the EVAP solenoid and one going off to the pipe to the vacuum canister.
