Yeah currently we have about 8°C but I don't think the temperature itself is a problem. Ok then I guess I am going to check all the coil packs and spark plugs and hopefully find something suspicious. Should the coil packs have an issue: do you have any recommendations which one I should get or should I just go with the OEM ones? Thanks!

The car currently has a OGS boost controller, which it came with when I imported the car from Japan. It is running on about 11-12psi. It also has an aftermarket intercooler and an aftermarket APEXI air filter.

Hi there! I have got a problem with my R34 GTT and before i try to do anything, i wanted to ask you guys if you have an idea what the problem could be: So - my Skyline R34 GTT drives quite normally up until 3000/3500RPM. However, I can't get over said RPM because as soon as I hit that, the car just puts in a limiter (at least it feels like a limiter). It also begins to stutter and it is misfiring after i step out of the gas. There's no difference in the engine being hot or cold, the problem persists. In Idle the car runs not drastically smooth, but also not really rough. When i try to go "gently" (I'd say < 50% throttle), I sometimes manage to get over 3500RPM, but even then the car starts to stutter. There is no check engine light on. I have looked around and saw some people saying, that the spark plugs/coil packs or the MAF could be faulty. What do you think? Thanks and regards, Lenny.
