Ding Ding Ding! That is very likely the issue. Nothing against RC or any other Inector Cleaning service. The factory side feeds are usually nothing but a headache once they have been sent out for this service. Spend the money and buy new ones. Not cheap though.

 

How long did they sit after they were cleaned by RC Engineering? FWIW, I had a set cleaned by RC which sat a few months before installed and used. They had issues from the solution used for the cleaning and not being used in a timely manner. I had to have the injectors re-serviced, but the next time I installed them in a timely manner (and ran the car a bit).

 

Only about a month at most.

 

Or just put in used stock ones... But leaking injectors is easy to test with the stock rail setup anyway.

Will do. Can I do a fuel pressure check?

 

That won't help, fuel just leaks back to the tank.

Unless it is a full sequential/emissions setup then it is hell on earth.

 

It's not terrible if you've done it a few times but I see your point.

Did you use RC Engineering's o-rings? I had issues with those:
