Thanks for the warm welcome everyone
As the project continuous i'll keep you posted!'
Unfortunally we've hit a kind of a bump that set us back some time.
It's got something to do with the ''limp home mode'' the car has got in.
The first few months nothing was wrong, then all of a sudden it got into the limp mode (has to have something to do with the car not having ABS/ASR). We've tried running the car without the ABS module since its got no ABS, then the speedo wont work cause we've managed to adapt the speedsensors(which work). We've had the car diagnosed, they could'nt get a read out so we did it the analog way. At first faultcode 16 appeared, which never came back after reset. Now faultcodes 27/28 appear, even after resetting them. At first, restarting the car / reconnecting the battery like measures seemed to help, now its stuck in there for about a month!. Also it seems the transmission is in some kind of limp/emergency mode, it only shifts when its about 2500RPM, sometimes it immediatly shifts into 3rd after first. All the oil's and filters have been changed.
Also the car starts difficult recently, the sparkplugs were all black eventhough they 're brand new bosch plugs. We've replaced them again, cleaned out all the injectors, tried different ignition coils. All the distributor caps and rotors have been replaced also. It only starts if we pull out the fuelpump fuse and start it, after its on we put the fuse back on and it works. All the problems are recent, before it worked just fine, thats what's bothering us.
Anyhow, i think i should be in another section for further questions/info.
Thanks again for the welcome!
