Missing Problem R32 Rb20

[britishbulldog]

Can anyone give any suggestions as to what could be the cause of the following problem on my sons Skyline R32 RB20 Single Turbo.

Car has a slight splutter/misfire when at operating temperature but not when cold.

Spluttering/misfire at constant motorway speed ie 80, 90, or 100 but as soon as you accelerate it evens out smoothly only until you come back to a constant speed then splutter comes back again.

We are at a loss, Can anyone shed any light.

Thanks

Tony

If you are mechanicaly handy, I would suggest giving the aac valve a good clean out, im sure there is a guide somewhere on this forum on how to do it!

If it's working fine at cooler temperatures and bad at warm, could it be that your plugs aren't the right heat rating? Maybe get colder rating plugs?

Cheers,

first id try playing with ur igniter module, pull the plugs around when its missing, if its not that pull the plugs out individually in the coilpacks, eventually ull source the cylinder having the problem. chances are its a coilpack problem, if not check ur spark plug etc.

if you have a frontmounted intercooler, check the tubing, check exhaust to see if there's any major leakage, check spark plugs and always use premium or high octane fuel.
