High RPM Hesitation/Fuel Cut and Glowing exhaust manifold!!!!!

[DarkCaporaL]

If I remember, Splitfires come with the harness, but the reviews I have read are hit or miss.

Probably around 15+ people on here have bought Yellowjackets and they have received nothing but good reviews.

A new harness from Nissan is around 150$ if I remember, so it comes up to around the same price if you get Yellowjackets+Harness vs Splitfires.

OEM Nissans are also good, but not cheap.

sweet thanks man. DO you know any sites that sell them?

[DarkCaporaL]

OEM Nissans you can order from any dealer.

Splitfires I've never bought any so I'm not sure, but Ztune or Daryl@Tunerlab can prob hook you up.

Yellowjackets it's this website http://www.performance-wise.com/page63.htm. Or you can pm performance-wise directly who's a sponsor on these boards. This was the group buy thread from earlier this year: http://forums.gtrcanada.com/showthread.php?t=43292.

Okay so i have an update. I was looking at my car the other day and i thought it was the exhaust manifold getting red hot but i think its the turbo? I have included a picture with an arrow pointing to where the red host metal is. I could be very wrong but i dunno. Any one help me out?

pic: Its heating up red hot right in-between those two metal shields? Help please

yeah thats the exhuast side.
i think its normally normal t have a glowing turbo ect after a hard drive?

if you pulled your plugs all out and none of them were deathly white theres nothing to worry about.

[pmurr181]

yeah they were white. I just grounded my fuel pump to get 12 volts so ill see if its still hesitating. Could it be the fuel pressure regulator?

[pmurr181]

or could it be AACV? FI so does anyone know how to clean it cuse i searched and didn't fin anything.

[love_boost]

i dont think the AACV can be the problem.
if you havent already checked that the TPS voltage is set right? and have you checked the fuel pressure?

[pmurr181]

haven't had a chance to check fuel pressure yet, however i check and set TPS to 0.49 and i just was driving and did maybe one pull and the exhuast got red hot again. I am running way lean, but i can't figure whats causing it.

[love_boost]

have you changed the fuel filter yet?

[pmurr181]

Yes i have first thing i did. Do you know what type of guage i have to use to test the fuel pressure, or where i can get one.

[love_boost]

you ould get a FPR with a fuel pressure gauge built in and possibly fix it, or atleast know what the rail pressure is.

i think you can buy something from most part stores called a fuel pressure test kit for around 30 dollars, or just any ordinary fuel pressure gauge and t into hose or get a section of hose so you dont have to cut the stock hose.

[Skym]

There should be a 1.5-2 inch diameter or so pressure gauge that screws into to brass T fitting. I saw that setup on a Skyline.

The stock FPR is rising rate. As revs rise, so should fuel pressure. If fuelpump or FPR is weak, could be the cause of lean A/F ratio.

okay sweet guys thanks i am going to try to figure it out and will report back.
