ok so i be modding the car for a while now, i have whats on the sig. But when i installed the unorthadox UDP i been having missfires, so i have BHR coil kit comming soon and i just put in denso racing plugs (Heat range of 27 lead and 9 trail) now before i did the plugs the CEL stayed on and or Blinked at me but never went away. not that i put the denso plugs in the CEL blinks at me or it goes away for a min then blinks at me again. Anybody have an idea of what might be going on????? And with all this going on it realy does not feel like its misfireing. she runs like a raped ape. I did scan the CEL it it tells me its missfire detected. Can anything els be going on from the UDP???

Thanks for the help guys...

I would ditch the denso plugs The heat range for the denso leading plugs are 27 and trailing are 31. The Stock NGK plugs heat ranges are 7 for the leading and 9 for the trailing. So i would stick with the stock plugs.

turn key to on position
tap brake pedal as fast as you can until the oil pressure needle sweeps across

you must do this if you take off or replace the crank pulley

resets the memory..your Eccentric shaft position sensor measure speed of the shaft when it sees it slow down too much inbetween fires it throws a misfire code(that a misfire the shaft will slow down since now pressure from burning mixture is pushing the rotor around hence turning the e. shaft)...and liek said above taking off pulley you need to reset.

Its pretty much like a crank shaft position sensor... Dont need to be a rotary nut to know this...and the name is kind of self evident imo lol.
