idle speed

  1. 2.3L Talk
    Aloha, Had a question about my 2.3 idle speed. Where should it be? At start up it runs about 2100 after a few minutes of warm up it drops to about 1000 rpm. Thanks for your help. And I noticed the throttle body has a sticker that says don't adjust idle screw CCW. Refer to manual. anybody know...

    For a 1965 289 both manuals i have say to adjust the idle to 500rpm in drive. I did this and the engine runs smooth but now i go down the street doing 30mph without so much as touching the gas. Now I like that the engine is running well but I dont want to have to buy new brake pads every 2,000...

    I have a 89 mustang lx and when i get it started it sets at real low rps ( 500 ish) before coming up to 1500 and settle back down to normal idle. Sometimes it doesnt take off but but will hit a few times then die. To me it feels like it might be dumping fuel. O2 going out maybe?
  6. 5.0L Tech
    I have a 1986 EFI 5.0 HO which has a rough surging idle. When the car was given to me i replaced the ignition switch because the car would not stay on unless i pressed on the gas. Then i replaced the spark plugs and the coil and it ran a little better. But the idle speed drops really low every...
