Hi all, I’m new here and new to skylines in general. I just got an R33 GTS-T RB25DET.
The previous owner only had it for about a year and wasn’t very mechanically minded and couldn’t tell me much of what was done to it by the owner before him. Long story short I’m having an issue with the revs dropping when I’m coming to a stop with the clutch in. Neutral or in gear makes no difference. The revs slowly drop as per normal but 1/4 times they just go all the way to zero and it stalls. The car runs perfectly fine otherwise. This leads me to believe it’s a sensor issue. I have taken the air box out and cleaned the filter (looks pretty clean and new anyway) and I have sprayed about half a can of cleaner through the AFM. This made the car a bit smoother in the lower gears, but the stalling is persistent. I’ve read many things here before posting this, I’m really at a loss as to what to do. Reset the ECU? Check and clean more sensors? I don’t know.
as far as I am aware the mods done are:
- 3” straight through turbo back exhaust
- 14psi boost
- A front mounted intercooler has been fitted
- turbo timer
any help is appreciated, thanks.
