DEI fuel rail shield write up

[Jerry Bransford]

I'd seen that listed before at work! Always wondered what it actually went on. Do you think it would be beneficial to put it on all injectors, or just the number 3 for the TSB?

Wrap it around the injector at the location of the misfire. For me I just had a #3 misfire so that's the only injector I installed it on.

I could definitely see doing it without disconnecting everything. I just wanted to clean everything, and I had to change my CCV stuff and valve cover gasket anyways.

Many ways to do the same thing. Some times my OCD takes over.

Yep! I end up cleaning and touching up things more than actually working on what i started with. I'd kick myself in the ass if i left something filthy and awful underneath new shiny parts.

I see. I'd actually never had a CEL come on. Just very rough idle around 300-400 RPM until gave it enough throttle while sitting, or air flow while moving. So hopefully this will be enough.

Rough idle until enough cool fuel filled up and lowered the temp of the fuel rail.

Yep, that's what i was figuring. So far I've drove about 150 miles, and haven't had any issues akin to it heat soaking.

In your 16'th photo, your injector is cracked, you should consider looking for replacements. believe it to be a somewhat common thing, dont believe it to be a critical issue but something to keep on your mind for later on service.

I checked all of mine while doing this job and didnt find any with cracks, but good write up and the added suggestion of new injector o-ring seals

The kit actually comes with new o ring seals! But yes, all of the injectors have small cracks. I plan on pulling the engine within the next year and building a stroker, so figured I'd defer the injectors til then.
