I have a 93 Chevy Cheyenne 1500 4.3l v6 tbi about a
month ago I was driving down the road and my truck just
died I pulled over looked under the hood realized one of
my injectors wasn't fireing off so went to autozone got 2
new injectors still nothing so I got it home from a buddy
with a trailer I replaced the distributor and was able to
drive it it drove fine for about a day then I took it on the
highway and it started to loose power by the time I got to
work couldn't go over 35 mph so tried timing it and
nothing when the truck is idling it surges up and down
and it will barely move now please help

had one do that to me once. believe it or not try unplugging the o2 sensor. if it runs good after that that needs to be replaced pretty soon or it will suck gas pretty bad or atleast mine did.
