Rough Start - Something Seems Wrong

DIGItonium

There's no L-shaped box for the intake anymore since it has the GTM kit. Gosh I'd hate to look for pinhole leaks. I'd rather it be the vacuum lines than the gaskets, though. It's a pain to have to take everything back out. I'll give it another run this afternoon as a sanity check since I did slightly tighten a few bolts in various areas... hopefully I didn't end up in your situation from over tightening.

no not a lift, just floor jack on one side of the car in the proper jack location to take a 1 min look.
last week I got the service soon light and had a code for maf sensor. nissan wanted to void my warrantee cuz of my gen 3's but after some arguing they replaced both. still have been having the random limp mode problem but other then that it was running perfect all the way home.
I have art pipes also so no cats

RBfastback

the 2 codes were p0101 and p010b.
either way nissan replaced both MAF's.
I have an uprev tune from feaver racing (zfeaver) and I got the tune the same time I got the gen 3s, gthaus exhaust and art pipes. so my afr was perfect as of about a year ago when I got the tune. originally I had k&n filter but last month I changed them to the aem dry flows that stollen sells for the gen 3's and also put on HydroShield from injen.
it's at nissan now, i gotta drive this in the mean time lol

apparently it was my driver side throttle body causing me the problems, they replaced it an everything was covered under warranty.
here's the work sheet

car runs amazing now.
I usually have the throttle lag/limp mode problem every day sometimes every other day but so far so good.
will de if that was also the problem

Jordo!

^^^^ Ah, Martin probably tuned you, right? He's a good buddy of mine -- your tune should be good

Looks like you had a bad throttle body

I've heard of that happening on these cars -- rare, but it happens. Unless you had the TB's off that's almost certainly just a random part failure and it's highly unlikely you will ever have the issue again.

The code is for a bad IAT sensor -- also weird, but both failures were on same bank so looks like you just had bad parts from the factory.

Glad it got resolved!

yeah martin seemed like a cool guy!
I've never taken them off before so I think I just got "lucky".

thanks for all the help with problem solving! i always appreciate it!

it sucked driving the murano, no fun factor

two months ago this problem appears in my Z, I 've been reading all the forums looking for the solution , and after talking with my mechanic, he suggested to clean the MAF, Throttle Body and the K&N filtre.

The MAF was OK, but the throttle body was really dirty, lot of oil and dirt. After a nice clean my Z is running great, and the problem never come back.

Its been 5 days without a problem.

Hope this help someone.

Certain cars (GM) cleaning the throttle body can fix so many poor running conditions. Also this k&n don't help with sticky oil gathering on the throttle bodies, just my opinion as I've seen it numerous times.

Man skimming through this thread makes me so glad I left the industry last year. It's scary out there with shot gunning parts. Not once unless I missed it did I see a residual fuel pressure test done. If they had done that they would have found the pressure not holding. Then cut off the fuel line and see if pressure holds, in your case it wouldn't because it was the injectors leaking. Would have saved them all the trouble of fuel line, ECM, fuel pump guessing. Lucky for them Nissan you don't have to drop the tank to change the pump or even worse corvette saddle tanks (15hrs labor) just to find out your wrong.
