How did the mechanic determine? Did he/she run diagnostics? The mechanic is desribing what the PCM intiates -"limp mode". You should have a check engine light on regardless.
Make sure your check engine light works. - Turn your key to the run position without starting. Does the check engine light come on?
If so - I think it's just what torkum suggests. Also clean your MAF sensor.
Yea , don't go for the ECT CHT yet unless diagnostics were run to determine. Other than that , sounds like a bad guess to me.
