Before I get knee deep in fuel, and injector costs, I want to be SURE that I've located the culprit. Should this do it?
Engine misses when warm. Compression & Spark ok.
As I've gleened from Bentley and other sources, I can pull the harness wires very breifly from each injector to note any lack of rpm drop. Pulling the offender should have no effect on rpm.
Secondly I am going to pull the fuel lines (with towel) off the fuel bar, disconnect the bar and pull it and the injectors. I will switch a non-suspect with the suspect. Reinstall.
****Do I need a new o-ring for this temporary switch?
Then test as before, noting rpm drop. Cylinder with suspect injector should have no effect.
Is there something I am missing?
TIA
