...its not that hard. Might we worth checking the ohm readings on the rest...they may be failing as well. Then its up to you to decide how many to replace or to take the jump to newer style injector conversion. The plenum / injector write up is here: clicky If memory serves you can just pull the fuel pump fuse under the hood instead messing with the kick panel to pull the relay out. I've done the dremel method on the middle injectors...so most of them are doable. I will mention - buy some new injector cap allen screws...the phillips head ones get boogered up pretty easily and you don't want to have to deal with a stuck one of those. Ever.
