ok so here we go again brand new turbonetics kit installed on 05 performance 350z i fixed the smoking problem but now the car doesnt want ot rev past 5 grand and whne you try to get into boost the car hesitats and spitts and sputters it kinda sounds like the car is in limp mode but last nite i drove it to town and was taking it easy and tryed gettin into it and it took off like a bat out of hell didnt spit or sputter and reved way past 5k now today its doing it again any help is appreciated.

 

lol, problems one right after another. As far as i know, limp mode wouldnt let you go past 2500. It does that to protect the car.

Do you have any codes?

 

yea the two bottom o2 sensors my scanner said o2 sensor low heater voltage summin along those lines i believe but i cleared it and it didnt make a difference,

 

Does the slip light come on and you lose all power??

 

o2 sensors wouldnt do that. i would check all the vacumm lines. check if u have any sensors not plugged in. do u have one of those cheap scanners??

 

i dont belive so i thoguht the tires were spining and the vdc was kicking in i turned it off and it still did it

 

i kinda thoguht they wouldnt i hope it anit chep i paid 100 ducks for it

 

Not sure if this is the same but if you're hitting a limp mode cut right before 5k it sounds like this. http://www.jimwolftechnology.com/wol...E_4700_RPM.pdf

The denser the air the more saturated the MAF gets.

 

thats pretty much what it was doing i cleaned the maf unhooked the battery and double checked everything to make sure it was tight,no kinks bends or anything like that put it back together and went into boost fine but is still running rich 10.0 rich and was starting to miss uptop so i think i need a tune... so how did jimwolf go about fixing that problem?

 

is your car an 04? sounds like your TB is staying open

 

05

 

Do you have a rev-up motor SC?

 

personally i think its a TB issue.. but you should read this thread https://my350z.com/forum/showthread....=throttle+body

his issue had nothing to do with the TB.. on the second page he gets it all fixed..

 

I just got my car back for the same reason "LIMP MODE" and apparently most of the 350z's have a recall for the gas pedal assembly and the sensor on the top is messed up and sends bad codes to the UTEC or whatever computer that u have, i just changed the whole gas pedal assembly and utec and no problems whatsoever, that problem drove me crazy for 4 months!!!!, the codes that i got was P2135 TPS.

ita an 05 performance nonrevup

 

ill check thta out later it was raining last nite when i took it out the roads are dry now so ill see what hapens on my way to work

 

so after driving into work i found that last nite it wasnt cutting out it was spinning the tires, today i got itno it pretty hate fully and every time i ran it till bout 6k and it was fine im still seeing an amount of smoke i think my catch cans are contributing to this im going to unhhok them and see what happens the car still needs a tune though, and im not totaly convinced that just cleaning out my maf fixed the problem i was having although it mie have.

 

Shouldn't be getting into it without a tune man

 

^ yea i know i want to get the bugs out of it before i take it down to mike
