Misfire?? Check your coilpacks.

Check your compression on all cylinders.

Have you tried a new set of plugs?
They don't last for ever.

Last time I was changed the plug

Maybe before one month

 

[fourtoes]

I presume they're gapped correctly?
What do the plugs look like when you check them?

 

[r34 spec nur]

Become black too much

And when come black the engine doesn't start

Pull the plugs off the coilpacks 1 at a time while the engine is running and see which cylinder is not firing .
Have you tried spaying Carb cleaner round the inlet manifold to see if you have a blown inlet gasket . When spraying the rev will rising if there is a blown gasket

Does the engine drive normally, but just misfire on idle?

 

[r34 spec nur]

No not normally in driving and not normally when stopped

 

[Nexen]

if its a blown inlet gaskets the misfire will go away once turbos start to spool .
My gtr would misfire up to 2500rpm but after that it would run fine . That was a blown Gasket

 

[Natbrat300]

Still slightly unsure about what exactly the engine is doing; is the smoke white or black, does it miss from start up or just when warm , does the miss disappear when revved stationary or when driven?

It sounds similar to a problem I had with mine a while back, which turned out to be a broken coolant temperature sensor wire causing the engine to flood. Symptoms were poor hot starting, stalling, low engine speed misfire due to poor combustion and black smoke on acceleration. The misfire disappeared on hard acceleration. Also the plugs were very black and became unusable in next to no time.

I would have a look at your wires.

No not normally in driving and not normally when stopped

 

[r34 spec nur]

Its missfire from start

 

[Natbrat300]

Have to you replaced ignition amp?

 

[r34 spec nur]

Yes I replaced ignition amp

And no different have

Same problem

 

[Natbrat300]

If I was you this is what I would do.

1. Swap coil harness with a good one, if not done already.

If one plug is getting fouled up.

1. Check compression.

2. Check injector.

If all the plugs are fouled up.

Check and clean all the engine earths.

Get the map checked.
