so as part of the restoration of my 1986 924s I had the engine out for a reseal etc and the engine is now back in the car however while trying to set the idle/co2 we have found a misfire/poor spark on cylinder 1.
pull the plug lead on cylinder 1 no effect, other 3 leads noticeable engine change,tested the spark at end of lead less than 2,3,and 4
replaced as part of refurb
Plugs and leads
dizzy cap
fuel filter
we changed the plug to another cylinder and it was ok, resistance check on plug lead and coil also ok
12v on each of the coil terminals with ignition on
continuity check on the green wire from the coil to 9 pin plug ok
resistance check on plug lead bang on
so any suggestions for what else to check much appreciated, may be a red herring however the rev counter has also stopped working I cleaned and checked all electrical plug connections.
I have read a fair few threads on the speed/reference sensors which appear to also be the driver for the rev counter (and green wire from coil ?) so still have to check the gap at these sensors
would the car start if the gap was out ?
the engine ran fine when we took it out the rev counter also worked so pretty sure its electrical/loom/sensor
all vacuum pipes have been checked
any wisdom appreciated on any particular checks required
