just put the z6 head and im having a couple problems. ok well first off it wont start. it starts when push started. the car started fine when it had the a6 head on it. and when it is started by push starting it will idle until you rev it to around 3 or 4k. idles fine not rough at all. im using the a6 dizzy the valve cover ground is good. please help...

 

where's the timing set at? that all right....
what ECU are you using?

 

im using a pg7 and im not sure about the timings. that would explain the not wanting to idle but any one have ideas about the starting problem?

 

Does it crank over and not start, or does not even crank over? Are there any codes on the ecu?
