90Q 10V Idle/timing issues.

[madwolf_uk]

Brief history, when purchased car ran with rough idle upto 1500 RPM approx, above that revs and drives fine.

Suspected air leak so split the IM and changed the 2 hose's to the IAC ( 1 had a piece of copper pipe shoved in it ), plus a small one at the back down to the IM ( cracked), filled a hole in the side of one of the pipes on the IAC, changed 2 crank breather pipes (leaking), cleaned everything up and re assembled with new gaskets.

Still sounds like its got an air leak but cant see where from...

Also found out the Dizzy had been changed as it wasnt running so timing probably out, got the info and checked the crank and cam marks, lined the dizzy up and it doesnt run. Turn the Dizzy about 15 degrees anti clockwise and she runs, all be it a touch worse than before. Since found out the Dizzy is from a KV engine, this is an NG, dont know if this is an issue though, marks on the Dizzy different maybe?

Spark plugs look ok, new rotor arm and dizzy cap fitted, one lead has a little nick in the outer insulation, taped up for now, leads look new, Knock sensor outer insulation is peeling away in various places, also taped up for now, MFTS appears to be playing up as temp gauge only works half the time.

Dont know how relevant the above bits are, but not quite sure where to progress from here, any help appreciated please
