i mean chocked as is not enuf fuel/oil/air going to the plugs
i'm guessing the feeling was some sort of 'hesitation'??
fuel/air/oil will have nothing to do with the performance of leads.
Fuel = 2 rich or 2 lean. richness can cause misfire in a system with poor ignition, lean would not really be affected
Air = intake/timing issue
Oil = in the intake means you have bad blow-by from piston rings.
But as stated by SLOWEGG, if the replacement did improve the response then your leads would have been on the way out caused by high impedance.
my car sometimes is hard to start -
I think its either:
spark plug leads (one has a split and is taped up)
my fuel filter is blocked
other than that i dont know...
i replaced the spark plugs but it still does it, it takes a bit for it to turn over..
just so u know...i found in my engine, that having oem leads and ngk plugs dont really suit....my engine started choaking coz my oem leads were too thin for the plugs....so i had to get thicker leads to suit the plugs i'm running....so if u got oem plugs go oem leads....if u go aftermarket, get ngk...those leads only cost me 80 bucks....retails for around 110 i think
That's because if your ngks were iridium, those need higher voltage than the old ignition coils can provide. That's also why older cars have copper or platinum plugs instead of iridium.
^^^Then yes it is an ignition issue unless your running hell rich.
how do you know your fuel filter is blocked? you can't really know unless you've pressure tested on either end. i dare say if it was THAT blocked, you can tell by squeezing the hose on the output end.
When i had the bigger plug gaps it was harder to start until i replaced with a stronger coil.
Even though spark arcs are far in atmospheric pressure (like 1cm plus with spark plugs)... remember that the density in the combustion chamber resulting from compression makes the plug harder to spark.... that aside, means something is weak in your ignition system and could be many things such as:
- Dizzy rotor
- Dizzy contacts
- bad leads with high impedance
- damamged/corroded/internally corroded plugs
- dying ignition coil
- A dead Ignition Control Module will prevent your car from starting altogether.

Thank you sir!! That is an un-commonly mentioned fact!!
This is further backed up by the tech article TODA AU posted in another thread in regards to iridium conductivity
Might need to get new leads soon. The OEM ones have done abotu 150,000 k's. How long are they meant to last. Is there a visual sign when they start to wear out??
