Right recently built up a 8v digi with 3a bottom end and a fast road cam. Been having a few issues getting it up and running right. Took it up to stealth on Friday on the back of the trailer as I was struggling to get the ignition timing right. Runs like a dream when warm but now i have got it back and its cooled down im having real issues getting it to fire. When it does eventually fire idle is pretty rough and trying to rev will cause it to cut out. This gets better after about 10mins of running. Popped the plugs out and it seems as though cylinder 2 and 3 aint firing properly. Have tried new coil, leads and sparks and the spark seems ok on the block. Have checked and both fuel pumps prime ok. Anyone got any ideas? Could it be the injectors?
