My engine dies on low speed (in hold ups)when the AC is on. I ve already clean the throttle and oxygen sensor, cannot accertain fuel pump pressure, but the car works fine if the AC compressor not ON.<\/p>\n

\n

Idle speed can be adjusted but the use of a scan tool<\/a> is required. One thing to check before you get into that would be to check the PCV Hose connections and condition. Check the the connections and hose for leaks. There is a chance that a Code P0505 – idle control system, may be set in this condition. Check the PCV hose and intake for leaks if code P0505 is set.<\/p>\n

Idle Speed Adjustments<\/h3>\n

Curb Idle Speed<\/h4>\n
    \n
  1. Ensure engine is at operating temperature.<\/li>\n
  2. Connect scan tool to DLC.<\/li>\n
  3. Turn power switch to ON.<\/li>\n
  4. Turn scan tool ON.<\/li>\n
  5. Follow scan tool manufacturers instructions.<\/li>\n
  6. Idle Speed: 600-700 RPM.<\/li>\n<\/ol>\n
