hi guys,
i have a C30NE engine (12V) and i would like to clarify the correct timing of this engine, should the crank rotation sensor should line up with the region of the crank pully (that has the gear like notches) where it is missing a notch, ie a space where there should have been 2 notches/ teeth, and #1 piston at TDC and the distributor rotor has a notch on the tip of the rotor should line up with a notch on the distributor housing in the region of #1 cylinder spark plug wire.
currently the crank rotation sensor lines up with the crank pully (region that misses a notch) when the distributor rotor points to # 5 cylinder spark plug wire... the engine starts and runs (easy for a Motronic 1.5 system that pulses the injectors in banks: 1+2+3 together then 4+5+6 together and the coil sends the spark respective of engine RPM which the rotor directs to the appropriate spark plug... when revved, it revvs well, but when held at a constant revv above idle, there is a serious missfire problem with rather frequent exhaust backfires, the oxygen sensor signal fluctuates from 0.18V to 0.89 V, the engine idles smoothly, spark plugs were checked for spark (injectors unclipped, plugs put onto plug wires and the engine cranked), plugs cleaned with carb cleaner and gap set to 0.035" and reinstalled), fuel pressure was not checked (awaiting delivery of a fuel pressure testing kit), though has battery voltage at the pump +ve terminal
does any one have access to a workshop manual on setting the timing correctly???
