Ok please can someone tell me what the sensor is on the intake tube I have a bbk cai and read in a forum that to help my engine to stop irratic idle I am suposed to disconnect it does anybody have any advice what happens is that every so often my engine will drop to 300 rpm and almost stall and then climb back up to normal idle it happens more often than not and I cleaned my throttle body replaced iac and reset ecu please please help thank you

 

MAF sensor it is called. A mass air flow sensor is used to find out the mass of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the ECU to balance and deliver the correct fuel mass to the engine. I would leave it connected.

 

Ok I know about the mass air flow sensor sorry I wasn't more specific there is another sensor that plugs into the intake tube that I have no clue what it does but I am trying to figure out why this form is saying you are suposed to unplug it with an aftermarket intake

 

Yeah when i put my new cold air on there was a new spot to plug it into

 

If you have a pre 01 that is a intake air temp sensor. After mid 01 it is built in to the MAF sensor. Unplugging it wont do anything except cut timing because its sensing a high reading whun unplugged which make computer think its hot air forcing it to cut timing and power
