87 Daytona Shelby ZTurbo 2, 5 SpeedFWD-P Stage 3 Calibration, 2.5" Exhaust w/o cat or muffler Upon start up it runs great for approximately 20 seconds, and the starts to miss.Misses under vacuum conditions; runs great in boost.If I set the timing at 8 vs 12 btdc, I pretty much lose the miss at vacuum, but lose ~ 3" of vacuum at idle and lose ~ 2psig and responsiveness under boost. Vacuum at idle with timing at 12 ~ 18-19". Vacuum at idle with timing at 8 ~ 15-16". After replacing the O2 sensor, the idle is surging with timing at 12, but idle does not surge with timing at 8.Things I have done or checked: Cam Timing - Found it off by one tooth. Reset it and gained ~ 3" of vacuum at idle (timing at 12).Compression - 2 cyl at 140, 1 at 138 and 1 at 138Leak down Test - Will not hold, leaks into crankcaseHEP - Mopar, have swapped with others, no changeDistributed - No slop in shaft, shutter - no wobble, has been epoxied, new cap - wires lock securely, new rotorNew Ignition Wires and Plugs - have used Champions and Autolites. They look great, slight rose tint on insulator. Mopar PCV and PCV 'ell'New Coolant Temp Sensor - Voltages and fan on/off okVacuum Lines - Replaced all lines with FWD-P Silicone lines distribution blockNew Coil - NAPAFuel Pressure and FPR - good, although the pressure leaks down to ~ 30 psig with key offO2 Sensor - Replaced Bosch with NTK, and verified voltages - ranging from 0.25 to 0.85 VChecked Grounds - Found one missing and replaced it, but it made no differenceInjectors - When I got the car it had 2 different injectors in it (3 of 1, 1 of another). I replaced them with a set of BWD/Niehoff 57224 injectorsSpark Test - at least 25 KV all cylindersNo CEL light, although I did have codes 22, 24 and 35. I assume due to messing with CTS and due to idle surge. Will reset with timing set at 8 to see if they return.I have been through everything nearly twice. Any advice would be appreciated.
