So thought I would post a quick update Ran the codes tonight and came up with AFM code Then got my multi meter and checked the voltage on the plug.... nothing. So restripped and housed the plug.?? Perfect. It must have broken or come loose when I took the airbox out.. Thanks so much for all your help guys.. was awesome to narrow the issue down Thanks again

ok great. I'll check it tonight hopefully. Our of interest does it jump straight out of that mode once It was plugged back in? Or did you need to reset the ecu? Cheers for the help all

Hi, ive teed it off the BOV for now. know its not good practice, but im convinced that isnt what is causing these issues... surely that would just mean i would be over boosting, which isnt what is happening here? By the sounds of it i might have problems with the AFM ? ill try running the codes from a thread i found.. http://www.skylinesaustralia.com/forums/topic/266512-reading-nissan-fault-codes-ecu-fault-codes-how-read-them/ reckon thats the best way forward? before jumping at buying a new AFM? Cheers all for your help appreciate it. Matt

Yeah I guess anything is possible. I'm thinking ill check the codes and check for the afm alarm. Are you sure the series 1 ecu has limp home mode?? Recommended??

Thanks for the comment. Certainly no rags in the piping. been really careful everytime i take it out. I havent touched any piping from the AFM back, just the intercooler piping. one of those photos shows the AFM and the first part of the piping, looks stock to me. funnily enough it might even be something to do with the AFM, its doesnt like going much about 2500.. would it be making those sounds now if it was in limp home mode? from memory i have disconnected the airflow meter and it doesnt too anything to help or change the symptoms in the vid.

Hi There all, New to posting but have been here reading avidly since Sept. Have bought myself a R33 Series 1, and loving it to bits!! it was stock, and have since put in a Just Jap 3inch cat back exhaust, running beautiful, no problems. Then about 3 weeks ago decided to install a Just Jap FMIC Kit. I read loads of guides, then got all the original piping out etc, all no problems. This is when the issues started. Have installed all the piping, using all but 1 of the stock silicon joiners supplied (on the hot side of the intercooler 3" to 2.5" reducer). Idle is FINE, however as soon as it gets to boost, it just chokes, like its cutting out... I thought this was a boost leak at first, but have removed ALL the piping twice, and checked with soapy water for any boost leaks, NOTHING. all clamps are exceptionally tight, and rock solid from what i and 2 friends can tell (fairly experienced with this kind of thing). Have a look at the video, and you will see the issues im having. i havent touched anything else, just this intake work, and this is the head ache i have no. Was hoping that someone would have had this issue / can help diagnose, cause im running out of ideas. here is a list of things i have done. Changed all intake piping. custom built a mount for the front pipe so that i didn't need to trim the fan blade and also help the front pipe sit flush checked all pipes, tightened all clamps Disconnected the battery for a number of days (to reset ECU??) checked connection to AFM (just wiggled and sh!t but all looks ok) have tried pulling the vacuum feed i have used for the actuator doesn't make any difference - (have heard that should use a line on the intake, and i will, once i have diagnosed this problem, im not convinced it is causing any issues) Thats about it, please let me know if you have any suggestions ideas. Have also included a few photos to perhaps help...? Matt
