    Stock Injectors or replacement

    Hello all,
    recently i have run into a problem. I will be driving along at about 2500 RPM and will jam on the gas in third gear. instead of getting power delivery i get a shaking and sputtering. feels like it misfires but no codes are being thrown. I replaced the fuel filter, it was very very dirty. problem appeared to have gotten better. until 50 miles later, i got the same problem. Looking at my injectors i can see that they are purple and are Siemens DEKA 80. how long are these things supposed to last? what replacements can i get? car is a 2004 with 98k in miles. has new plugs, ignition coils. new valve cover new oil separator. Has 0 codes

    Thoughts?

    Do me a favor and try unplugging your DISA (just the wire plug) and see if you still get the stutter.

    DISA was replaced within 100 miles of owning the car

    I'd prepare for a fuel pump, buy one and keep it in the trunk. The original pumps go out around there, give or take 10/15 thousand miles.

    That has nothing to do with my request. It's worth a shot and worked on mine. I left it unplugged for a week or so and then plugged it back and haven't had an issue.
