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?
