xe running problems

[chug1106]

Finally got my redtop engine back into my nova,anyway it smells like its overfuelling and running all lumpy.
so far i have tried different ecu's,air flow meter,wireing loom,temp sensor for the ecu,rotar arm and dist cap, ht leads and different coil.

so when i was working on it,i earthed it onto my van battery as i was using it to jump it,and got another set of leads and used them from nova battery,to engine and to chassis to see if it was a bad earth, and it went fine, but now its not again, by the time i tried all the things above the engine was obvisly warm so dont if this is why it started to run fine when i earthed it and just a coinsidance.

any ideas what this could be?
lamba sensor?

Coolant Temperature Sensor. Well known to cause rough running. New ones can be bought for not alot. I got mine from Euro Car Parts.

anyway of testing it, can you bridge it out and should it run better?

right changed the coolant switch and the idle control value,still the same

its poping and back firing what im guessing is timing,the belt is on with all marks etc
anything else
crankshaft sensor?
could some values be sticking as its sat for 5months?
