Could it possible be the timing is out?.
Re-assembled strictly in accordance with the Manual, The timing thought has crossed my mind but trying the easy ones first, a lot of work to expose drive train & check pump timing again, I will also try & run with the Catalytic converter off, will be noisey though, The thing that stumps me is when you start & put foot on throttle it is like it is not connected to engine, the revs slowly climb up and if you put the air-con on the revs drop a long way below normal idle. hate the rotten thing
