Idea for DYNO

Since the NO1 failure is the Injectors maybe a special post on Injectors is in order.

Start with the poll - HAVE YOUR INJECTORS FAILED YET?
Box 1 - NO
Box 2 - Yes at under 10,000 miles
Box 3 - Yes at 10K to 25K miles
Box 4 - Yes at 25k to 50K miles
Box 5 - Yes at 50K to 75K

you get the idea and in the text post the owner could tell us what year ZR-1 and which brand of injectors they replaced with and any other notes on their project.

I am interested as to when the various MY's fail due to the 10% Ethanol on average.

We know the MY 93 and up are supposed to be OK with Ethanol ---Right??

I see a lot of 90 and 91 MY's going out and I figure it is just a matter of time for my 61K -- MY92 to have the ETHANOL INJECTOR BLUES

[Locobob]

My 368 is a little shy of 80K, think I have replaced almost everything in the entire car at least once

[sammy]

Previous owner replaced all injectors and a coil pack. Other than that, not sure of any major work.
