No spark in cylinder one somtimes

[bajansuperman]

can any one tell me what is the cause of this i changed plugs and wires so those r fine, my fpr is set at 20 stock injectors standard ecu wideband show car idle at 11s to 12s when all four cylinders are working and 17s and up when spark in cylinder one is out

Well it has to be either dizzy cap , plug or lead dude.theres no way a coil pack can be at fault.

new dizzy cap new plugs new wires

have you tested the other cylinders to see if spark is missing on those as well?

if its just one cylinder, then its most likely the wire, plug or cap ------and you said you changed those

plug gap?

whats that explain

[Bristol glanza]

if it was me. take all 4 plus out, earth them on something on the car, turn the car over, check for spark on all 4. it maybe dizzy cap or leads.

spark plug gap i am guessing?

[bajansuperman]

i did it by putting a long screw driver in the wire and laying it on the cam cover saw spark

[bajansuperman]

sounds like a boat and when i pull number one wire no change in idle
