Hi all ive put my c20let back in now but seems to be running lumpy, as if its only firing on 2 or 3?

the engine management light is on and the boost guage seems to be bouncing because of the rough idle.

Ive checked all vacum hoses, timing, and its had all new dizzy leads rotor arm and new plugs spaced correctly.

Any ideas please lads?

check the two plugs at the back of the cylinder head i think (dont quote me) can be mixed up and might need swapping

check all the earth connections

paperclip test the faults that will help

get a new coil as it may be nakered
