Question about 1991 Ford F150
I drive a 1991 F150 5.8 351. When its at an idle, it bogs upon accelerating, then picks back up. The idle is also fairly unstable right after its started. I have changed the MAP sensor, TPS, and the idle air control valve. any ideas as to what may be wrong?
Listen for a vaccum leak.also try disconecting bat for 5 min the reconnect and start truck and hold idle at 1500-2000 for 5 min. this resets and teaches computer to self adjust
