Car: E320 97 Japanese spec
I had a warm start problem which seems to be due to a leaky injector. I replaced all six injectors with used ones and the car starts as normal now (six injectors with their fuel pipes and valve are replaced).

Is there anyway to check and identify which injector is causing the engine to flood and resulting in warm start issue.

(note: before changing the injectors, i changed the MAF, plugs, CPS, used injector cleaning material. all of them have failed to solve the problem)

guys, is it so challenging or near to impossible

What's your mileage? I read from the others that injectors no need to change too early, usually it is the o-rings leaking and needed to be changed. Can you post some picture of your old injectors or the DIY procedure?

do you have "check engine light" on? what's the error code?

the car mileage is about 170,000 Km. I reviewed all the posts related to warm start issues which pinpointed a leaky injector. I diagnosed the problem to be due to leaky injectors causing engine flooding as per http://www.benzworld.org/forums/w210-e-class/1418940-98-e320-flooding-what.html . well, i dont know what o-ring is but if you mean the metallic pipes where the injectors are fixed on and the fuel is delivered to the injectors then I have replaced it with the injectors. I never read that this can cause the flooding too(my bad). I replaced everything for less than 150 $ (not in US) including labour so it is not a big issue.
as for the pic, I dont have any since they were changed by my indy.

as for the codes, there were no check engine light and honestly i have not checked if there are some bending codes.

I was just curios if there is a way to inspect a bad injector since my indy told me it is not possible so he changed all the six injectors.

This post is related to your question. It is the same 1997 E320.
