Hi everyone.

A mate of mine is having some troubles with his cossie.

We have tried to changenot sure on all the technical names)

-Ignition module

-phasesensor
-cranksensor
-coil
-dissy
-plugs
-pluggleads
-blue sensor back of head

-changed ecu

-earth
-measured clearances on sensors etc.

Still runs like a scooby(or a cosworth with bent valves)

The only thing we havent changed is the map sensor, but doesn't change much when we unplug the vacuum, just revs higher.


Any ideas ? The car runs smooth when the temperature gets higher and he floors it. The plug on cyl 1 is soaking, the rest is normal.

Maybe injector ? We measured and every injector gets the same current, and he tested each one spraying out in the air, and looks like it's ok.

Vids:

Normal:

checked the inlet manifold gasket?

Nope. Will the car act like this if the seals broken ?

In the second vid it clearly is just 1 cylinder, the same 1 all the time that is not pulling it's weight and missing.
I would try to identify that cylinder by pulling plug lead/s with it running, then try a new plug.
A plug that has ever ben soaked in fuel won't always work properly afterwards, but it's something individual to a cylinder so try plug and injector, even swapping injector over with another cylinder to make sure it is the injector and not the wiring to it, if the problem transfers then you know it's the injector.

Yes we tried to pull each plus lead, and at first it was number three. But now there's no change in the sound when we pull number 1 and 2. Tried to change plugs but still the same, I suggested to switch the injectors last night, so maybe thats the problem. Only number 1 gets wet with fuel

Thanks for the replys
