Changed the Coil Packs - Now Code PO303
Tried to change just one pack but that was only an incremental improvement so I changed them all, since I had been receiving a random misfire code. Much improved but still throwing a code PO303 but now it is specific to cylinder 3 which now gets me down to either a fouled plug, a bad wire or a dirty injector. Will address that tomorrow along with some other issues.
Did some scans and LTFT'* are still going as high as 16.4 on any deliberately brisk throttle application, although the STFT'* only fluctuate between maybe -3.5 though +5. They all drop to 0 on 0 throttle which is better than I was doing with the previous engine.
If it doesn't rain tomorrow maybe I can give the engine some more attention like the supercharger fluid, thermostat mod, change out the fuel filter, etc.
Any suggestions or comments are appreciated.
