Hey there everyone, im new to this forum and wanted to try and get some answers. Well, i have owned my 2001 ford lightning since "new". its got about 127,000 miles on it (unfortunately) Recently, it has just been running like crap. The idle has been going haywire. On first start up, the idle goes up as normal for "warm-up" but after driving a little while the idle stays up around 1500rpm. Once parked the rpm's go up to about 2100rpm. i have changed the idle control valve, and tried changing my tune but nothing seems to be working. any suggestions would be appreciated. Just ask if you need more details about the problem. Thanks
