[RomeoR33]

Hello Fellow Skyline Gurus

I have a weird problem which I seem to have not been able to fix or find the fault, and would like some advice.

I have a R33 Gtst with a Rb25det non neo. Currently the car is overfueling ridiculously at idle. The car is completely stock with the addition of an aftermarket exhaust and CAI. No aftermarket ECU etc.

When starting the car cold, the car starts perfectly, and runs great, but after the rpms drop, the car starts bogging and smoking black and attempts to stall.

Any advice on what to look at to fix this?

Thank you

A failed ECU temp sensor with default to rich mixture and cause this problem, as will a leak on the FPR and a bad MAF.

you may have a leaking injector or injectors, bad MAF or bad FPR. its hard to tell over the internet. im use to having my hands on the car

I would change the ECU temp sensor first and re-solder the contacts inside the MAF as there known for corroding, then the FPR and finally if problem not fixed have a smoke test done..
