Fuel cut after repair

I changed clutch, timing belt and lot of smaller parts for my Glanza.

After repair it started to performing bad on high load. It works quite good on small load on low rpm, but on highway speed it does not accelerate as good as earlier and it also having kind of disorder in running, although it seems to charge well according to original led pressure meter.

I get also engine check light on, so I check the faulty codes and it was blinking 34, which means too much pressure. I wonder if there is some hose or wire loose or if I forget to connect something? I have been checking wires and hoses, but not found anything yet. I do not know how this original boost solenoid is supposed to work, and where that pipe goes? That is something that was bent during removal of timing cover, but can it raise boost if it disconnects from another end? Seems that I cannot even see another end, so I may need to disassemble some parts to connect it again... Does someone have diagram, or link to diagram, where I could see where that another end goes?

Did check hoses and reset ecu, don't know what it was, but did not lit check light anymore. Still it did run quite badly. Now I bought cheap timing lamp and ignition was about 2 degrees , set it to 10 and now it seems to run Ok. Somehow I thought that it won't affect on ignition timing if I change timing belt, because marks stays same. It is not excatly in center of hole in upper mark, but it wasn't earlier either. Must be that it is now "wrong" in another direction as it was earlier. Must be some slight difference between these belts.

Hmmm. Now I read the instruction for setting timing:

It says that ecu needs to be in diagnostic mode when setting timing, mine was not. Maybe I need to do it again :-/

It's certainly possible you are experiencing fuelcut if the boost level is above stock levels (.65 bar) but it's hard to rely on the factory boost gauge.

I'd check the timing again with the vehicle in diagnostic mode to be sure, if you are getting a loss of power high end you may have to inspect your timing marks again. The need to check/set the ignition timing afterwards relates to how even slight movements in the mechanical side can have a large effect on engine behaviour. I think we've all had this sort of fun after a cambelt change lol.
