I have cleaned everything out etc, the car started up and run smooth from the word go. On a run it first went well then missed a beat a few times as if it was blowing the spark out.
I came home swapped the new coil back to the original Nissan unit and also fitted my original plubs. Went out again, seemed ok then missed once. Found a nice quiet road and did a full race start all the way to 100+ and it pulles like a train, did the same on the way back,...it also was ticking over fine when I go tit home.
Hmmmm ill take it to Loton as it did seem fine at the end.
It does seem to be running a touch rich on the AFM, woundring if the Injectors need a clean? Will see how it goes in practice.
