I have got my Nissan Bluebird ARX that is not revving well, but when you remove the air pipe after the airflow sensor it revs very well and power increases. what may be the problem? it drops idling when the engine gets warm, when engaging in drive it switches off.

Hello,

It sounds like you have a MAF that is not working right. Lets run the codes to see what is going on. Here is a guide to help us get started:
