Rb-20 Running Like Shit...

[maso]

hey i got a problem with my 32, it runs like its dropped a coil real shit and unresponsive struggles to boost...

now i'v changed the coils and unplugged one to check if it got worse or stayed the same but it got worse everytime.

Changed the plugs, AFM the black square thing on top of the motor... i cant think of anything else..

i got biggerfuel pump and i can hear it running fine, put injector cleaner in it... still the same.

the only other thing i can think of is i have a gtr fuel rail and injectors on my motor... and i know they have resistors wired to them is there any chance that one of the resistors are farrrked.?

Will the car idle or does it keep dying?

If ECU is not tuned for injectors, could be the problem. If injectors are yellow top, I think they are stock GTR injectors and red top for GTS injectors (unless they are red top 550cc RX7 injectors). One injector not working is one area where engine can run rough. Leaking intake manifold gasket on head to intake manifold is another that can cause rough running. Same with leaking metal headgasket that's blown the seal around cylinder.

leak between the afm and turbo, makesure all clamps are tight and sealed.

Also you could have too much blow by in the cooler.Clean this out degreaser or something.

Unless the ECU settings are altered to account for the extra flow, it will be running rich EVERYWHERE.
