Does it slobber and sputter or just flat quit dead like you dumped the clutch? Mine is acting up similar, embarrassing to say but it happened last February. Running fine in the morning, sat in a parking lot for 4 hours, fired right up as normal, idles fine for 2-3 minutes. I pulled out, then Iím going to call it a cough as I pulled onto the highway, felt about like a backfire on a carbureted gasser when you push it a little hard when the choke is still on. Was fine for 100 miles, started doing it worse and worse. Napa was open and had a cps in stock, no change. New dealer Motorcraft cps, still no change. Itís basically all OE, 165,000 miles, and had a damp valley, I was thinking air. So parts got ordered, thrown in the front seat, ďwill get to itĒ,,, and, well, just got to it. New pump, new rubber lines, cleaned resealed bowl and fpr, cleaned and checked bowl harness wiring and ipr, and still the same symptoms.
Big thing thatís strange to me is that itís a pretty violent miss - when it cuts out driving, itís a hard buck, feels like a backfire. Another site said it sounded like a high-pressure oil leak, probably injector o rings, going to try that next.
Any ideas on how to pinpoint which injector it might be? Can you run these with the valve covers off and see anything?
