defo got the injectors set up correctly on the PFC ?

how many miles  left ?

[LRP]

yes the maps been checked over was running fine just coasting along and started to miss?? confusion?

[strange_days_uk]

blocked fuel filter ?

what was the injector duty and was there any knock ?

[LRP]

brand new filter knock was 4 not sure on injector duty? on my understanding the crank angle sensors control the timing of the front and rear rotors \'right\'???

[BlitzBoy]

so u changed the Apexi to use 1680 injectors?

[BlitzBoy]

and the lag settings

[LRP]

yes its all been set and checked by greg the guy that does the mapping at rx motors??

Coil pack wiring,have you changed that/checked it.

I had very similar symtoms recently on another car,it turned out to be coil pack wiring loom.

[LRP]

we hav a spark at every lead im wondering if i hav a break in the loom from the crank angle sensor to the ecu so the timings not 100%

[LRP]

forgot to say tryed another apexi ecu mapped with same engine spec still not cured carryed out wiring checks on all fuel and igntion loom nothing abnormal running out of ideas ? going down the alarm myth now tracing alarm wiring and removing the immobilizer side of it !!! HELP

Throttle position sensor? Probably not, but worth a check to make sure it\'s in spec.
