while engine is at top dead centre. dowels facing 12 o clock timing marks line up perfectly. at first we were only getting spark on 2 cylinders. so i got new coil pack for it . we have spark to all cylinders now but still running rough as guts. anyone have a similar problem? we put new head gasket on arp head studs. it has balance shaft deleted so we did not line up oil pump timing marks
 
Post some photos up of the cam timing marks. Did you do anything else at the same time ... more specific details please
 
How did you get it running on 4 cyls. I assume it was ok before ? Did you take the cams out, and maybe not bleed the HLA's down ? Did you machine the head face ? Replace cams ? The cam timing marks almost never line up, and can be a little deceiving some times ..
 
seems like it in limp mode. no power. spark plugs are wet. has anyone had a similar problem. if it is crank angle sensor would these be the symtoms? tdc was double checked with long screw driver on # 1 piston.

^ This. The best way is with the cam cover off, lay a steel rule on it's edge on the head between the cam gears to line the timing marks up.
Are you sure you have the high tension leads in the correct order?
Cyl 1&4 should go to one coilpack and cyl 2&3 go to the other. 4-1-2-3 is how the factory leads line up iirc.
 
yeh mate , that s how we lined up the notches on the cams with the ruler on the head. we put the timing light on and its 17 degrees past tdc so might be ecu related. it has a really old adaptronic ecu
 
could be injectors. took plugs off on 2 injectors and no difference in idle. ill get them serviced and see if this is the remedy. if not could be the module.
 
Balance shafts are 180 degrees out

*edit* just saw you have deleted them.

What about CAS. Sometimes that can be put back 180 degrees out too.
 
i bought a sonata coil pack and we reversed the spark plugs and car started normally. happy days. cleaned injectors 1 flowing too much fuel 1 flowing not enough after being cleaned. i bought evo 9 injectors off liam cedro which arrived today which should fix the idle. thanks for the replies guys
