Starting new thread to sum everything up and start fresh:
Original thread: Ideas as to huge MPG drop since overheating?

Problem:
-Used to get 21-22mpg, now get 12-13mpg
-Figured out rust in system, possible filter split.
-Replaced injectors about 100mi before found rust (possibly clogged?)
-Power is sluggish and seems to hit a wall with power @ ~4500rpm. It'll go higher, but it seems to just stop producing power and I can feel a possible knock (so I stopped).

Items replaced/done
-Fuel Tank flushed (have not removed though)
-Fuel Filter Replaced
-Fuel Distributor + EHA Brand New
-Ran pump into jar before putting new distrib in....No rust found. Gas was clean.

So now...

Pulled injectors and found some dirt...No way dirt should be there. I'm guessing before I found the rust, it contaminated the injectors.

This is what I found: (KEEP IN MIND, These injectors have < 100mi on them!! They are practically BRAND NEW)



[1] -- SINCE they are practically brand new....anyway I can clean them successfully? I have put them in a bottle full of B2 Chemtool overnight....think it'll clean them enough or will I need to do more?
Is there a way to successfully backflush them? Since these are mechanical, is there a way to somehow open the nozzle?



[2] -- Plan to flow test system at distributor (injectors disconnected, lines on) into plastic bottles to ensure a) double check no rust b) double check strainer is not blocked. Sound a good idea?

Any thoughts or ideas for approach to solve this? Car hasn't been driven in 9months....Just moved house to somewhere I can work on my car now, so time to get her back on the road!
