I think the mass Airflow sensor is bad i dont know. When i went to go install a Weapon R intake tonight I had all the stuff hooked up lines and stuff and when i turned it on the thing would not idle at all it would just stall. But then when i disconnected the mass Airflow sensor plug the car would idle great I tought it was fixed and all but then the car would not go over 2k Rpms the car would kick back down to 1000 rpms. Like an speed limiter, i could not get the car over 2k rpms. Is my mass AirFlow sensor bad and if it is how much do one of those cost. Also my cel came on. I need help so i can figure out what to go buy at my Nissan Dealership tmw. Please help guys im stumpted and ****ed.

 

Check your instalation. No lose or forgotten hoses? Plug in your MAF and reset your ECU.

ECU

If you still have problems you can test your MAF with a volt meter, but don't worry about how to do that just yet.

 

MAF's aren't that expensive if you outta warranty.. I got one replaced on a 5thGen for $69 brand new. Your 4thGen should be a lil cheaper.. You don't have any air leaks or anything like that right?

 

allright i got 0102 which is mass airfolw sensor or circ. fault then i got 0304 which is knock sensor how in the hell did i get that then as it seems i got 0401 intake air temp sensor..

 

everything is hooked up right no leaks and **** but it is how out and my friend was sweating and the way his arm was bent over the battery he got shocked in the battery i odnt know if that has anything to do with it or not
