Zedrush Posted August 14, 2007 Posted August 14, 2007 After having the nismo exhaust, high flow cats and plenum spacer installed, I noticed that my rev metre when in parked, idles funny, I sat for 5 mins watching it as it fluctuated between 1000 rev then drop to 500 (when I thought it was going to turn itself off) then back up to just under a 1000 revs again constantly. Is this normal after such mods or is this telling me something? My brother just took his car to Nissan and they said there was some air escaping from where the plenum had been inserted and that it will need to be rethreaded as the screws wont go back in. On mine I opened the bonnet turned on but cant hear any whistling noise of air coming out from the engine bey, just hear the note of the engine dropping below the rev then going back up again Quote
M13KYF Posted August 14, 2007 Posted August 14, 2007 Is your AC on. Never found the Z particularly the smoothest on tick over with the AC off. Quote
Guest prescience Posted August 14, 2007 Posted August 14, 2007 I recommend that you do an ECU reset - as listed in the FAQ forum Quote
Adam@Z1auto.com Posted August 14, 2007 Posted August 14, 2007 prescience I think has it correct - once you do the plenum spacer, you should do the TPS (throttle position sensor) reset procedure Quote
sl114 Posted August 14, 2007 Posted August 14, 2007 This one here http://www.350z-uk.com/forum/viewtopic.php?t=89 Quote
Guest prescience Posted August 14, 2007 Posted August 14, 2007 and the TPS one is found here (where the above also came from originally) http://www.technosquareinc.com/350reset.htm Quote
Zedrush Posted August 14, 2007 Author Posted August 14, 2007 found out one of the screws on the plenum cover was lose, hence excess air escaped causing a drop in the rev monitor, getting it all fixed and sealed again tomo cheers all Quote
N15MNO-Daron Posted August 20, 2007 Posted August 20, 2007 Glad to hear u found fault.. Did u notice any positive changes when the plenum was installed? How much was the part and installation? (by the way shud we avoid the garage who fitted yours?? ) Quote

(by the way shud we avoid the garage who fitted yours?? ) Lol definatly avoid the garage that fitted mine, I got a specialist in 350z and Jap cars doing all my car care tuff now including services and remap and rolling road, costs a bit more but at least I have peace of mind and thats worth paying for Plenum spacer does improve performance slightly speak to Adam@z1 auto.com for full info Quote
nixy Posted August 20, 2007 Posted August 20, 2007 Just out of interest - what revs is it supposed to idle at? Most cars I've had are just over 1000rpm but coincidentally on Friday I noticed mine was nearly as low as 500 although it didn't seem like it would cut out. Quote

Thats fine Nixy, if you have the air/con on it will rev a little higher (700) rpm. Here you go Nixy. http://www.350z-uk.com/forum/viewtopic ... light=tick Quote
