My 2008 Chevrolet aveo will not get over 3000 RPMS and the chevk engine light is not on

What is your question?

I've replaced coils plugs etc air filter oil and filter and It just will not let reve up to 3000 RPMS and 40 mph it's a 5 speed manual transmission

What makes this problem better or worse?

It does this from the time its cranked up

How long has your 2008 Chevrolet Aveo had this problem?

2 weeks now
