Hey guys, i've got a R34 GTT, thats running a rough and i've got no clue as to how to fix it. Its your standard Rb25 Neo, but with aftermarket intercooling tubing, a pod filter and a HKS G176 BOV, recently i've changed the oil, sparkplugs, rocker cover gaskets and half moon seals.
Firstly on a cold start, it starts up and idles perfectly, but when re-starting it up ( Warm start ) the car won't continue to run and will only run if I hold the accelerator on for 5-10 seconds at 1000-1200 RPM.
Secondly sometimes when I'm accelerating at a normal speed, i hear popping sounds from the engine bay and I loose a considerable amount of power. The only way that i've been able to overcome this issue is by revving the engine over 4000rpm and then it goes away after a little. I also get this same issue at the top end of my revs, its almost like i can accelerate to a certain point and then it begins to pop. Its like the engine can go harder but is being stopped by something.
Thirdly, My check engine light comes on after about 5-10 minutes of driving. My dad and I found that my turbo had melted my O2 sensor wires, and still after re-wiring it, the check engine light still comes on, so I have no clue as to what to do with that.
And lastly i was wondering if its normal in turbo cars to get oil on the inside of your inter cooler / turbo / intake tubing. There is a decent amount oil along the sides of the tubing that's got me worried.
Any help would be appreciated, Cheers.
