Hi Guys,
I'm really hoping someone can give me some info/guidance on some problems I'm having with my baby.
The car is a R32 GTST - RB20 stock engine. I bought it about 18months ago; it has approx 220,000 km on her. Major 200k service was completed by previous owner (according to him)
Problem 1 (first started occurring 2-3 weeks ago):
The car will start up normally, and will run normally at first. Then once it gets warm, after 40min to an hour of driving, it will start to sound like it has dropped a cylinder. It will develop a "put put" sound from the exhaust, start to backfire badly after acceleration, and would generally feel like it had no power. The car will not idle smoothly, and the idle will drop quite low (400-600 RPM). It will still get some boost, but it won't start to kick in until around 4k RPM. There is also a strong smell of fuel inside the car (with the windows up and no a/c or fans on), as well as outside the car.
The problem started out being fairly sporadic, but then became more regular (as in would occur within 30-40 min of starting the car on my drive to and from work)
Once the problem starts, it won't go away until the car is not running for a significant period (like overnight).
*First thought is to a leaky injector o-ring, and some fuel can be seen in the area around the injector. But have not removed it yet as am waiting on parts.
Problem 2 (started approx 1 week ago):
The car will start normally, and will idle normally. Then when trying to pull away in first, the car will seem normal until 2k RPM. Then it will bog down, and plateau at 2k, and will take 20 30 seconds to get to 3k RPM. The boost gauge on the dash (which is not in PSI) will read to -7, until RPM reaches 3K, and then it will come back to 0, and then start to boost up to +4 at 4.5K RPM (which is much later than normal). The same will happen in second gear, but not in any of the others.
It is hard to say if this issue occurs after a certain amount of time, or in certain conditions. It has happened straight away from starting the car, and it has also happened after the car has been running for a while.
I have had this problem go away while driving once.
So fingers crossed you guys can help! Thanks in advance, and if there is anything I can be more specific about just let me know
