R34 Gtt Issues...

[Carbon 34]

the tps on nistune cars is insanely sensitive my tps was no kidding a pube hair off and the car would go nuts , ashley put his laptop on it and even he said it was mad sensitive( i set it by ear and feel after my carbon removal of throttle plate lol) , check your throttle manifold gasket mine was a tiny tiny leak and the car wouldnt run good enough to even drive 10kph it would stall slowly , hunt around and misfire unreal just on boost had to use blue rtv till my nissan gasket came from the moon 3 days to get one here ffs

The tps can throw errors but its rare , once TB cleaned it was way off and i had to set by ear and feel till i had a laptop on it , the 34 manual has the voltage specs to test it

This maybe a shot in the dark but reset your ecu i did and it cleared my other issue ( nistune ecu base program) and unplug and use electronics cleaner on tps and cas connection and some silicone spray once plugged back in to repel moisture

i would seriously fix that T on the fuel reg a leak can run your motor lean - motor go boom in a flash and then you can pour the broken rings and melted piston out the r34 has a vacuum pickup in the back near brake hose vacuum? its rubber plugged from factory

Your sure the TB blade backside is clean a tiny bit of carbon fouls the idle and it hunts around while the tps tries to sort it out ?

if thats all good

Air leak between manifold and afm , most likely behind the engine area near firewall ( the maf sensor on firewall area ) or near afm

you cleaned the afm with maf cleaner and reset ecu ? checked the plug for corrosion ? oil film on hot wire and it all goes south ?

your airfilter is clean ??? pcv clean or removed to catch can with feedback loop ?

Plug gap set right ? clean ? And tight ? (Screw top plugs tight if that applies to yours ?)

Low voltage at fuel pump ? common issue with upgrades , check grounds by pump

If not then a bad spray pattern or clogged , leaky injector , dirty poor fuel ?

fuel pump clog if the car has ever had e10 or e85 in it , it dislodges tank rust and eats rubber even in small doses

CAS not sitting flat and tight or bad plug ? But that throws errors in most cases

Did you change your tyre air as specified ? common problem hahaha

And god forbid a timing belt flapping around on a broken idler pulley tensioner ( doubt it but they can break off and drop the belt !) that usually sorts it self out quick , leaves you stranded

go see ashley tell him troy sent ya his shop is behind hungry jacks area in hackam off south rd

mmmmk so after all my checks, it all came back clear... still have my problem.

But i spoke to matt from nistune, and he seems to share my thought pattern on the injectors being the issue.

Xspurt injectors are a modified bosch.

Some people love them, but im finding quickly most tuners do not.

either way i have purchase some new injectors, hoping that this will solve my issues.

sorry to bring up an old thread, but I'm just curious to know what the problem was and if you have gotten it solved? I only ask because I'm currently having this issue with my 1999 GTT and it's driving me insane trying to figure out what it is. Any help would be appreciated!
