Bad acceleration till you reach 2000 rpms

Daewoo 1.4i Oct 2000 , only 35000 Km about 22Kmilles, new fuel,air,oil filters. NO CEL ON.
The main problem happens when the engine is hot enough, needle just under middle.
The symtomps are: dificulties to accelerate, light jerks until you get to an least 2000 rmps, after those rpms
it works fine , but driving in town is a bit unpleasant.

Checked proper conecction to the Temp sensor and Air temp sensor . Don´t know if any of them
are not working properly.
Is the mix too rich ( It realy makes a bad mpg)??
Should I change both sensors??
How can I check if those sensors are working properly??
Any suggestions ??

Dude, check you vacum hoses are all connected up, also make sure none of them are split.

+1

also a TB & IAC cleanup will help, try some injector cleaner as well.
