    Hey all

    My vx auto just started missing a cylinder. I'm pretty sure i know which one. I had ongoing issue that seemed related to this so I recently changed sparkplugs and everything was working then mid drive one cut out.

    I think fuel is not getting to the cylinder. What test's should I be doing to uncover the issue?

    Thanks

    *edit additional detail*
    Previously the car would stall most morning after reversing then putting it into drive. going up some hills with lower revs would cause it to have inconsistent power until you accelerate some more.

    Pull both sparkplug leads off the coil feeding that cylinder and start it there should be a big blue spark jumping between the 2 coil posts and making a good crack sound if it comes and goes or barely jumps the gap the coils dead

    I did the test. There were come good cracks but not heaps. it jumped between the sparkplug looking top and one of the coil posts(what I assume that is anyway) but even then it would not consistently jump.

    So shes dead then? are they hard/expensive to replace?

    I compared it to other ones and it seemed to perform at least 90% of what the others did

    Unbolt the 2 little 7 or 8mm bolts and lift it off and fit a new or second hand one
