i've tried various forums, including here and had no luck yet... so here it goes


OK here is the story:
one day i was driving home from work, and my car started acting funny
(built d16y8 motor running on neptune)
i thought it was a vacuum leak, since i once had a problem similiar to this and my map sensor was disconnected (luckily i figured it out before driving it)

well this time, it got worse and worse, and i thought maybe I had a vacuum leak, but i was wrong

my friend also had the same problem as me... but his belt skipped a tooth, then a day later his car died... and compression showed a problem in cylinder #3

UPDATES:
compression results
190 180 190 190
leakdown test less than 1% across all four
no vacuum leaks (tested with a bike pump and a boost leak diy tester)
timing with timing gun ... perfect
switched out OEM fpr for another OEM fpr
installed a new ignitor coil inside my distributor
fuel pressure gauge installed... reading 45 psi at idle


Any other ideas? Could my RC injectors be bad? is there a way to test them out?
how about my oem fuel rail? i i have a couple spares laying around, but not sure if thats the culprit.
