check your fuel pressures.
fix ignition issues.

T77911S, Please give your thoughts on my pressure data. Have adjusted it both ways(rich/lean) with no change in misfire. Hoping it turns out to be the wires. Thank you!
System Pressure: 95 psi
Volume Delivery Test: Passed
Cold Control: 20psi
Hot Control: 35psi with wur vent vac hose plugged in. This is the reading with the engine running. Car has run great this way the hole time?. Only discovered this now after testing for misfire. At this pressure with the old injectors engine would run on/stumble quite a bit when turned off. With new injectors it shuts down clean, no run on. Did adjusted afr to 13.6 for this pressure setting.
Hot Control: 51psi with wur vent hose unplugged or reading with engine off and fuel pumps running. Note: did plug the unplugged vac hose so no leak. With the new injectors engine runs on alot and backfires after shut off. It runs on so much I felt like it would never shut off! Did adjusted afr to 13.6 for this pressure setting also.
