R33 Gtst Hesitation

[tom.33gtst]

Hey guys. My r33 has a slight issue when coming on boost sometimes on long drives.

It will cough and splutter just as it goes to come on boost then will clear itself out and take off. It only does this on long drives say driving on the highway for a while then you go to give it a bit and it will hesitate. Around town it never seems to do it.

It seems like its running fairly rich as well.

Any help would be much appreciated cheers

Check the following

Vacumm leaks

AFM (CRC Cleaner)

Coilpacks

Intercooler Pipes

Fuel Filter

Fuel Pressure Regulator

Spark Plugs (type / gap)

Lower boost (if running above 10-12PSI on stock ECU)

Check for ECU codes

That's all I can think of right now. Hope it helps, there are lots of threads on this type of issue or something similar.

Thanks for the help, checked half of those things out but ill have to have a look at the rest. I bought a tomei adjustable fuel reg so ill put that on and make sure it's running correct pressure.
