Got a problem with my 2wd Cosworth. It starts and runs sweet but after running for a few minutes it first starts to miss then cuts out and won't start. Remove plugs fit new it fires then the same happens! Every sensor is new, l8 ecu is ok done by msd and obviously works as car runs ok at first, timing is right, all sensors gapped correctly. Plugs when removed are black but not wet. Any ideas?

 

Ive got the same problem with mine,gonna investigate further tomorrow,you havent sorted it by any chance have you?

 

Not yet iv got a few ideas what to check but ain't had the time to go and have a look

 

sounds like its running very rich if its sooting the plugs up that quick my cossie used to do it too when only being moved in and out of the garage everyday or just left idling, would take a couple of days to do so though

 

What heat sinc do you have for both of the ign amps.

Both ignition amps are the original ones so have the original heat sink? Could this cause a problem? I havnt thought of this il have them off and re do them. Thanks.
