I have a 1989 f-150 with 88343 original miles!This truck has always been maintained by the dealer.The problem i am having is this.The truck runs excellent,but as i go down the road,it seems to "stumble",or miss..its real quick and then goed right away.I replaced teh o2 sensor as that code and code 67 came up on the scan tool.I am thinking the ignition control module might be going bad ?any ideas?..I know code 67 is the "neutral gear switch",but i cant seem to find any info if that might be causing my "stumble".Thanks for the help.....by the way...its a89,4.9l 6 cylindr,5 spd manual tranny...
