R32 Gtr Idols But Not Revving Properly

[Blown6]

HI ALL I GOT A R32 GTR 1989. HAS A APEXI POWER FC Z32 MAFS, CAMS, COOLER, INJECTORS THE NOMRAL STUFF

JUST HAPPENED OUT OF NOWHERE WHEN TO DRIVE IT STARTED IT UP MOVED OUT OF DRIVEWAY WHENT TO TAKE OFF AND IT DIES IN THE ASS.

PUT IT IN THE GARAGE AND SAT THERE WILL REV BUT WITH HESITATING WHEN U PUT URE FOOT DOWN LIGHTLY AND HOLD IT THERE BUT WHEN U STAND ON IT IT JUST POPS AND FARTS AND BACKFIRES THROUGH THE INTAKE AND WONT GO OVER ABOOT 2-3,000

CHANGED FUEL PUMP AND HAS POWER AND ALL GOOD

CHANGED FUEL PUMP CONPUTER IN THE BOOT AND THE RELAY NOT THEM

MAFS ARE BOTH WORKING AS FAR AS A CAN SEE. TOOK TOPS OFF AND LOOK OK. BUT NOT 100% AS I HAVENT CHECKED THEM ON ANOTHER CAR OR VISEVERSA

NOT TOO SHURE ABOUT COMPUTER HAVENT GOT HAND CONTROLLER TO CHECK IT OR ANYTHING

INJECTORS AND COIL PACKS ARE GOOD.

CHANGED COILPACK WIRING NOT THAT.

CHANGED SPARK CONTROLER OR WHATEVER IT IS ON THE TOP OF THE COILPACK COVER NOT THAT

CHANGED EXHAUST CAM SENSOR NOT THAT

TURBOS ARE FINE.

PRETTY SHURE ALL THE HOSES AND ALL ARE STILL FINE.

HAS GOOD FUEL PRESSURE.

IT SEEMS TO REV A LIL BETTER WITH HIGHER FUEL PRESSURE BUT CANT FIND OUT WHY IT WOULD BE IT SITS AT AROUND WHAT IT SHOULD BE ACCORDING TO THE MANUAL MAYBE A LIL HIGHER.

IF ANYONE HAS ANY OTHER IDES OR CAN HELP ME OUT WITH MAYBE BORROWING A MAF SENSOR OR ANOTHER COMPUTER THAT HAS ABOUT THE SAME MODS SO I CAN DEFINATELY RULE THEM OUT THAT WOULD BE SUPER. AND COMPINSATED THROUGHT HE BEER ECCONOMY OF COURCE.

Yeah sounds like MAF sensor problems to me. Need to get your hands on some good Z32 units to test.

[Blown6]

tested the volts on them and had mates computer in it with the hand controler and the volts when up on them but may still be the problem ill try get some known working ones to try

[Blown6]

just tested air flow meters on a mates 300zx all good. not the air flow meters

[BoyWhoCriedWolf]

Does it idle smoothly?

[Blown6]

IT IDOLS A BIT ROUGH DUE TO THE CAMS IN IT. ... BUT IT DOES SOUND A BIT DIFFERENT THEN BEFORE NOT TOO MUCH BUT. BIG ROUGHER

[blind_elk]

Dirty fuel filter?

[adamskill]

check the bov's

[Blown6]

had a new fuel filter only about 1000k's ago. havent checked the bov's but its getting boost so they cant be stuck open.

[Blown6]

all were wrong sort of.

found out by looking through the computer that all the settings for everything were set back to stock. computer has wiped and reset it self to the factory rb26 settings. so mafs were wrong injectors were at 100% and maps are wrong just needs a retune now.
