Message Sounds like one of your intake pipes is only half way on...

when you unplug the maf, it is not reading the air coming in, the motor goes into a closed loop mode basically. It is kinda like what is happening when the motor is cold.

But when the motor warms up, the ecu is relying on all the sensors to know how it is supposed to act. So, if one of your pipes is not hooked up right, you are drawing a lot of unmetered air, which means that based on what the ecu is seeing, it isn't supplying enough fuel for the right mixture. Check your accordian pipes.
