1jz timing issue
I need some advice from you 1j masters. I put my motor in a sc300 and it ran crappy and I noticed that both cams were a tooth off to the right of the timing marks. So I put a new timing belt on it and set the crank at zero and even put an extension in the cylinder to check tdc, then I lined the cams up with the marks behind them. So runs way better except under load it pops and cuts out and is not happy. The timing is at 4degrees at idle which it should be 10 I believe. The tps is set all the way to the right but even if I mess with it while holding a timing light on it it retards even more to like 2 degrees. I've double and triple checked my timing belt at tdc all the marks line up perfectly and I just can't figure out how to get the timing to 10 degrees. Out of gear it revs up fine idles ok a slight miss but not terrible, only under load it's pissed. Any help would be great thanks guys
