misfire on WOT
I have a 1998 type R and since i fitted a walbro fuel pump is seems to have aquired a misfire.The car drives fine if you drive 'sensibly' but if you plant your foot it misses like mad,could it be just the plugs/leads breaking down or is it a bit more involved?

Is it not over fueling maybe, did you cut of the 12 to 9 volt resistor?
just a thought though!

Yes i removed the resistor.After trawling through numerous posts on the resistor issue i decided to remove it and store it somewhere so im running at the full 12v i thought it might be pumping too much fuel in and flooding the engine at WOT but wasnt sure.I'll whip the plugs out tomorrow and give them a clean and a re-gap and see how it goes.Hopefully once the remap has been done it will run sweet again as it was only mapped for the std pump first time round

worth replacing plugs though.. set the gaps at 0.7mm etc..
