[QUOTE="DILLARD000, post: 1039297, member: 74901"] What are the OBD2 TroubleCode numbers? 1st thing to try, Carb\Throttle cleaner down the gullet. 2nd thing, remove & clean MAF Sensor with electric spray. 3rd thing, take ThrottleBody & IACValve off & clean. 4th thing, pull #1 wire, electrical spray & inspect for nicks\cracks, re-install with di-electric on boots\porcelan not metal contacts. 5th thing, take coilpack out, electric spray & inspect for nicks\cracks, check ohms. Primary should read 0.4~0.6ohm across pin4 to pin1\2\3, 0.7~0.9ohm across 2 coils pin1~2\pin1~3\pin2~3, open to frame all pins. Secondary should be 12~14kohm across each socket pair, open to frame all sockets. 6th thing, how old are your plugs+wires? If >75k Miles, they're suspect, replace & gap to 0i052~0i056. 7th thing, how old are your O2 sensors? If >75k Miles, they're suspect. 8th thing, any hissing vacuum leaks or obviously cracked vacumm hoses. 9th thing, recently cleaned\inspected\replaced the PCV valve & hoses? 10th thing, could be a bad\dirty injector? Hope this helps. D PS: Details of my adventures maintaining a 2001 Ford ExST at [URL]http://2001fordexplorersporttrac.fandom.com/2001_Ford_Explorer_Sport_Trac_Wiki[/URL] [/QUOTE]
