I dont have a pic but it is a air line,dont think for canister as this is on battery side behind headlight.The cannister has airline coming from driver side.I have cleaned TB infront of throttle plate ,I need to take it off and clean thoroughly,and I will also IAC.Car runs well now though with cleaning egr,and so far no SES light.My heater works alot better now wonder if that vaccuum line fixed it.thanks for replys.

Took a closer look and the line going behind headlight comes from Hvac passenger side firewall travels under coolant reservior to passenger headlight and then across to driver headlight and 3 elbows disconnected ,it is tough to reach and hidden but didnt really feel air coming out.I reconnected lines and hopefully this is my vaccuum problem with Hvac (no heat) and could this cause the maf sensor code if vaccuum leak or would the leak have to be closer to engine.thanks
Thinking of changing plugs and wires ,I have 3 square coil pack is there certain wires for this and do you know what kind this is.90 sse
