94 5.8 with code 313, need help
Recently my truck started running rough, missing at idle and even worse under acceleration. Gas mileage has dropped to about 10 per gallon and to sure what was up. Pulled codes last night with key on engine off I got code 313 “Thermactor air not bypassed during self test” which does not make sense since this code should read with key on engine running<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

Any help would be appreciated <o></o>
