Default Serious engine failure and following problems

Hi together,
some days ago, my Baja starts to have a loud knocking noise from the engine, also to feel on th clutch-pedal, occuring while accelerating. I took it to my subaru-shop and they found some metal-chippings in the oil and for sure there are one ore more bearings broken, probably crankshaft, as ist is feelable through the clutch...
So i hooked up a new shortblock and oilpump and let it be swapped. After starting the engine, the camshaft-sensor failed too, and has been replaced meanwhile.
But there is still a problem: engine starts fine and also is fine while cold. But when temperature reaches about 70į Celsius, it starts to idle bad, CO reaches 10 % and cylinder 1,2 and 4 are much to fat. Nobody in the shop and at Subaru Germany has any idea what the prpblem could be!
Everything possible, esp. ignition-parts and IAT has been changed without result.
Any idea? Anyone?
Regards and thanks for answer,
Chris

A bad temp sensor could make it hard to start or run to rich when the motor is hot. Also maybe they have the injector plugs switched or the timing belt off ?

Thanx for your answers,
I did get the CEL for the camshaftsensor and meanwhile crankshaft-sensor, too. Temp-sensor, belt and iginition was checked. Engine started fine and ran good until it gets temperature to warm idling...
And meanwhile the problem was found! There was some bad connection at one of the two engine-main-electrical-plugs! So I think, the rpm-Signal from the camshaft-sensor and/or crankshaft-sensor was interrupted or bad. After cleaning all connections two times, it works now!
Best regards
Chris
