Vehicle will not stay running unless I give it gas..
Hello everyone, I am new to this forum and really need some help!! I recently bought a 2001 Ford Focus SE, and it idles real rough.. Runs fine at higher speeds but soon as I lay off the gas and press it again, shake shake gobble google thing runs rough. I bought the car yesterday morning (sat July 13th) and today I went to advanced auto parts and got some goodies for the car. Idle control valve, throttle position sensor, Pcv hose (was closed up) thinking that would take car of the most of the rough idle.. And yes the car dies with the ac is turned on. So I installed all these parts and changed oil and other nick nacks, and now the car is running worse!! NOW IT WON'T STAY ON AT ALL!!!! It takes a couple of try's to get it even started. I've googled and googled with no luck. PLEASE Can anyone help me??? Thank you
