Another bad Injector

I,m getting very tired of this car I had another injector go bad #3 right behind the front plenum runner, was able to fish it out with out removing the intake. Is this going to be a common thing until I replace them all? Should I just sell it? Also now I think I have a fouled plug as I tore a O ring on the install and it flooded the car on startup . It idles ruff from 1500 rpm to 2000 and this did not happen on the last installs. POS!!!!

Much easier to replace injectors in rail once out of the car. Damaging O rings is common otherwise and hydraulic locking is a sure way to bend a rod.

There is a way to switch to the later rotary pintle injectors which are not so susceptible to ethanol if you have an earlier 1990-1993 G50.
