R33 Chugging Problems

[Ciny]

Hey guys,

I have a 93 R33 GTS-T, it has a few mods, T4 turbo, external wastegate, extractors, front mounted intercooler. It's my first skyline and she's perfect except for 1 small problem.

It drives along all nice and smooth, then she carries on as if she's about to run out of fuel, she has half a tank of 98 octane in her so she's not actually out of fuel, and the volt meter jumps around,

This happens either when I drive her normal or when I push her a bit and revs get up to 4k or over. I'm ruling out the coil packs as it doesnt feel like a missfire its a chug like im out of fuel, and the volts jump around, it does this 2 or 3 times then runs fine for awhile.

Anyone have any ideas on what it could be? I'm completely stumped.

Most probably the AFM, try the 'how to' on re-soldering the pins.

There may be a gtst one also, but they are much the same. It is usually the pins from the plug that get dry solder joints from vibration.
