The injectors basically squirt a quantity of fuel based on the pressure
given to them an how long the injectors are opened for by the ECU.  The
chances of them delivering more and then less fuel and back to more fuel
independently is going to be slim.

Have you put a fuel pressure gauge on the system?  Perhaps your fuel
pressure reg is going?  Have you removed the injectors and test fired them
to see if they make a nice 'perfume bottle' spray as opposed to just a jet
of fuel?  Perhaps is it a faulty engine temp sensor making the ECU feel the
engine is in warm up mode, then run mode, then warm up mode...

Subject: 85"1.9L What happens when 1 or more injectors go bad?please
help...

Still, having issues.....have found that will run lean then go full rich,
then lean then rich ....and so on......almost all we have left are the
injectors.... what do they do when they go bad.....I was thinking maybe one
is spraying lean and anothere is trying to compensate by running rich or
something....any ideas.....
