Sadly I had to use Bosch injectors in my car, like 2 years ago because monark nozzles were no longer being made and no one had any. So far the car runs and gets good mpg....but the idle seems to keep getting rougher...I imagine its because of the injectors but my blow by is so bad that I refuse to sink money into more new injectors....I need to check timing chain stretch and readjust the timing....that may help... But in my case I haven't had any real bad issues with the nozzles..
