oki my xr3i mfi has never started first time it's never really bothered me as i only use it now and again but i would love to fix it.
i have :
Cleaned the inlet and throttle body
Changed the air filter to a pipercross one and cleaned air box
Cleaned the metering unit the butterfly part
Given the car a service oil filter and plugs
Changed the warm up reg
Changed the cold start injector
Re timed the car after doing the cam belt
adjusted the fuelling using a c02 meter and my trusty mechanic that has been trained on k jet when it first came out

Put a breather filter on the rocker cover breather
Things to do
Change the coil
Replace the leads

Can anyone give me any suggestions when i get the car started i have to wait till it's warmed up as it has a flat spot from about 2-3000rpm. Any help would be briliant
