I have already started cost to rebuild vs getting a drop in has been a thought i know some guys that might have a few just dont have money at the moment might need to find a beater with a heater for the time beingI would crack each injector line whiles it's running and listen for any change in idle.
This will tell you how many cylinders are affected.
I would also start thinking about how cheap and quickly I could get it fixed.
I would go with trying to score a running engine off farcebook marketplace or Craigslist.
It sucks, no doubt.
These are cake to swap.
