Replaced 4G91 DOHC with 4G93 DOHC

[frankfula]

I have recently replaced my old 1.5 litre 4G91 DOHC manual engine (Saloon car) with a 1.8 litre 4G93 (from an automatic transmission RVR vehicle), and I am having some problems. The car keeps jerking when driving, has a hard start and generally revs very poorly. At first I thought it was the computer box, but I bought the exact one and the problem is still there.

What could be causing this? I really have no idea?

Thanks
