throttle body & sensor have been replaced. Still wont accelerate above 20rpms??

What is your question?

My car has had throttle body cleaned, then changed and a position sensor put on. It worked for a day. Now it randomly has the same symptoms it had originally. Now the last mechanic said it could be a MAP sensor, but he doesnt know if that will work either.

What makes this problem better or worse?

It's very random

How long has your 2006 Suzuki Forenza had this problem?
