My mechanic tells me that my fuel distributor checks ok, but that one of my injectors has an improper spray pattern. He suggested that In use a few tanks full of good fuel with Techron additive to clean it out. I've done that and the idle is still rough, sometimes barely noticeable, sometimes not.

Should I just order a full set of injectors and seals and install them myself? How much of a job is this? The injectors are on top of the heads and should be easily accessible - just unscrew the old and screw in the new. Am I oversimplifying? Is this a DIY job, or should I leave this to the professionals?

My mechanic tells me that no harm is being done and that the 126 is notorious for idling issues, by the quivering idle distracts me. If I can save the $90/hr. I'd like to!

Euromeister sells injectors for $35. each. Anybody know someplace even cheaper?
