Throttle body replacement

[Lukeys]

Good evening everyone,

After some issues regarding my Ls2 VXR purchased a few months back I replaced the TB with a genuine second hand one which resolved the problem with the car running perfectly albeit with some unrelated issues. The harness on the TB had a broken tab so I held it in with some cable ties which done the job.

I have now fitted a brand new one ordered from America ( which was about £380 including import fees etc. I done the relearn procedure ( but if someone could kindly please confirm what it is) and all the issues popped up again, safe mode, engine spluttering.

Now, as this TB was cheaper than the one listed on rockauto I may have now come to realise that it may be chinese ****. Im going to fit the old one in tomorrow and see if the problem still persists. Just wondering if anyone has had similar experiences with aftermarket ones. As I'm aware the silver bladed ones are non existent and I'm not sure if I want to pay for the only ones listed on rock auto unless they are close to genuine and reliable.

Thanks again!
