I have had a CEL for a few days and a rough eratic idle, and it is really sluggish to come off of idle, when I press the gas, it hesitates a few seconds before deciding it wants to drive. I have checked the air intake system (MAF) and I did now repalce the faulty O2 sensor. So it reads all happy on my little computer thing. What is botheriong me now however is that when I am not touching the throttle the computer says the throttle is at 18% 0.95v. Is it SUPPOSED to read this at idle? Or should it be at 0. Please let me know if anyone else knows and has messed with an Auto Xray OBD2 scanner.

I guess the next question would be, "what RPM is your car idling at?" 1996 Contour SE Sedan 4D (Royal Blue) Duratec V6 2.5L 24-valve DOHC Automatic 75,000 miles No Mods (unless you call the DMD a mod) Replaced EGR valve (gunked up), EVR (EGR VR), PCV valve, and evaporative emissions hose (cracked).
