As some of you may be aware ive been rebuilding my rev2 mr2.

Today i managed to get the car to start but now have some problems.

1.

When i start the car it fires up then idles up and down a bit.

It then cuts out, not splutters off or dies it';s more like its turning itself off.

If i try to hold the revs on it still cuts itself out.

Not sure what this could be?

2.

The plugs are pretty black, they werent when i put them in but are now.

Im assuming all the times cranking before firing drew loads of fuel and stuff into the engine so this should clear once the engine has run a bit.

Correct me if i am wrong though.

(I dont think its relevant, but i replaced the fuel pump with a walboro, i assume this is fine as i really dont want to have to change it again!)
