corrado-ek

Hi guys, my coolant/temp light flashing and annoys me like hell.. It's a 1991 G60 Corrado What have i changed ; -Coolant reservoir tank with new sensor -Black temp sensor -Complete dash cluster i think i changed everything related but still keeps flashing, however i need to tell one thing ; When i use a blue temp sensor instead of a black sensor so when i have 2x blue temp sensor the flashing stops...:banghead::screwy: Hopefully you can help me out

Changed vac hose to ecu, much better at idle now but still black smoke when i hit the throttle

Hello, When i unplug my O2 sensor/lambda sensor the car runs perfect, when i plug it back in it gets horrible. No stable idle, chocking and unburned fuel (black smoke) in exhaust. (O2 sensor is new, Brand : BOSCH)
