help with egr?
hi, i've posted a couple of times under windsor tech lookin for help? I'm workin on a 1988 f150 w 5.8 efi. truck very hard to start and keep running until i remove the vaccum line on the egr valve then it runs fine, but, mil light stays on. now wait- the valve functions properly as well as the evp (sensor) on top, there are no restrictions in the system. i've checked the tad/tag relays and lines the vac hold 1.0 hdg at idle.. koer code 31 and 44 help if anyone has had this problem?
