If you are going to do the job yourself, I would just do the one that pulled the code. After one time apart, you won't mind replacing the others if needed in the future. At a dealer, I might replace the 4 on that side. I feel that it's an easy do-it-yourselfer. Good Luck, Happy New Year

i would replace all 4 on that side imo. i wouldnt want to open it back up again a few weeks down the road for anouther injector, but that depends on your pocket I guess. if you can spring the extra cash then I would replace the 4 on that side.

nither side is very hard to do. the hvac case is not bad to work around. by the way I think that side is easer

Really? I can do that side without removing hvac case? what do you think about hypermaxx injectors, I saw a whole set for 1200 bucks.

O and the evap case all you need is a 12mm racheting wrench and you can tape a t30 bit to a 1/4 wrench to get the oil rail bolts off. also the stand pipe needs to come out of the oil rail before you remove the rail on that side

If it weren't for bad luck I'd have no luck at all... Hopefully it works out for you, though.

Just wanted to update thread, I replaced the #4 injector, truck is running great with no misfire, only issue at this point is the truck takes very long time to start,extended crank, was wondering if reflash will help, never brought truck in for flash yet. Still have cold start issue, runs rough 
once it warms up, run's great.
