Changed the engine from a 2002 into a 2004. Idle problems then 2000RPM

[guest3719]

2002 with 2004 engine 1.4S LH steering. 84HP

Hello.

What problems can arise when you change engine in a Jazz 2002 to an engine from a jazz with the 2004 engine (both 1.4 liters)?

I have problems with idle now 2000 rpm, I have changed to the intake manifold from the old engine.

What problems are there with this kind of engine replacement?

No engine light öights up in the panel.

Hope for help soon

Try to clean the EGR valve or swap it.
