Hi,Im having a couple of issues with my 91 4x4 cossie.

When first started from cold it wont idle and stalls but its fine when warm,

Second is that under full throttle the engine just splutters and the revs die down it backfires a few times and it cuts out,then just starts fine again its only under full throttle as soon as it passes 5000rpm?

Just rewired the fuel pump so rules that one out.

Many thanks for any advice
