Hey all...
Iv been reading the forum for a few months now, only just registered.
Iv read a few threads that seem to be similar, but just wondering if anyone can share any advice.
Im the proud owner of a clean R32 GTR, and it provides much fun and pleasure.
I had a problem with it about a month ago, and only knowing what i know about engines & cars through the magazines and forums i read, so dont be too harsh (im hardly a DIY mechanic).
The problem i had, was that i would accellerate but the car would jerk and not go anywhere. The revs would also not go up so i realised it wasnt a driveline problem, but something to do with my fuel pump / lines or intake / ignition & spark.
I took it to my mechanic (normal ultratune who it is generally serviced by) and he refered me to a EFI specialist.
He told me that i had faulty O2 sensors in my dumps, and that he would replace them as the factory ECU was getting different airflow readings from the AMF's and O2 sensors which was causing the engine to cut the fuel or inject too much (rich and lean etc) which was causing it to hesitate and not accellerate.
Cut a long story short, the EFI specialist charged me nearly $500 for fixing and testing the O2 sensors and to make sure that the engine was running ok. For the first week the car was good as new, but recently it has started again.
I was going to ring him and let him know that he hasnt done the job properly, or is it something else, like coil pack or sparks / fuel pump / faulty or dirty AFM's etc that could be faulty instead of what he has replaced???.
Any feedback would be great, as if im gonna ring him to give him a serve, i wanna be right or at least have some ammo to go with.
Again, im a newbie so be easy.... Has the specialist pulled a fast one and ripped me off????
Cheerz!!!
