well seeing how injectors throw fuel in the cylinder to be ignited i would say listen to see if it sound like youve dropped a cylinder but hey dont take my word for it

You can put a stethescope on each.
They should all click about the same.
should sound like a sewing machine in there.
can remove and flow test each I think Bently describes this do some searching .
can check voltage etc at contacts I think too.
I did a post previously with some part numbers for Bosch Ford TypeI and type II and III replacements
ie 17 19 24 lbs
New ones are expensive Denso I think make a good Hipo one $$$
ie 100each x6 == $600
You can buy decent remanufactured ones online. But the point is to upgrade the fule rate.
StarMavin says just get yellows from an old Ford at the junkyard.
I'm stil thinking of doing this.
Check your pressure regulator too ther are two types i has more pressure than e I believe.

yep the E runs at 2.5 bar and the i runs at 3 bar...but contrary to popular belief converting the E to 3 bar lowers the power due to an enriched mixture....
