will injector failure lead to engine damage?

[Ianfauchon]

Hey everyone, I'm new here and hoping you experienced guys can impart some wisedom on me,

02 PSD, bone stock, 207K, regular oil changes...etc.

I've had a fair bit of water in the system, and a few fuel gel ups last winter in which I had to run the engine fuel starved just to get power steering to be towed.

Its running a bit rough now, seems to have a bit less power, and if you hold it at 2000RPM in neutral you can hear an audible (and feelable) POP every 10 secs or and engine loses a few hundred RPM.

My worry is that I messed up one (#8?), some, or all of my injectors. In time i can replace them but im worried running it with bad injectors might cause engine damage (overfuelling a cylinder=blown rings, etc)

Any thoughts,

Thanks guys!

Ian
