Here's one for the Ford mechanic(s) ................
2001 Ford F150 4.6 4x4, 161000 miles.
It has a rough idle. When I test vacuum at the manifold my gauge read "retarded ign". Using Autoenginuity software, the front 2 o2 sensors are putting out between .04 to .7 volts, the rear O2 sensors are between .75 &.82 volts. I replaced the pcv hose & fittings, & idle air control valve. Cleaned the MAF sensor & throttle body.
Any help?
Thanks,
NT
