first i want to apologize my engilsh that could be hard to understand..
my buddy have an g60 rado and it has a little running problem..
after start it runs well for a while when engine is cold.. when engine gets warm problem starts..
the problem is next:
it idle just fine for a 15-30 seconds and then it starts to run very hardly and black smoke starts to coming out of the exhaust.. we shut the engine down and started it again and same thing happens.. then we start to check all the electric connections from the engine and noticed that, when we pulled the connector out of the blue water temp sensor the problem was gone and car starts to run well.. then we put the connector back in place and problem came back in 5 second.. on my own car that connector disconnecting kills the engine running, wich is normal.. both cars have almost the same specs on engine tuning..
then we tested for my buddys car how it runs in drive.. and it plays perfectly..
why that car works how it is working now?
sorry if text is hard to understand, but i hope u can help me and my buddy
Try disconnecting harness from blue cts and plugging into the black one (same kind of sensor but used for signal to gauge cluster) Any difference? If I read your discription right could also be the O2 sensor.. check connection, brittle wires, good ground is a must, etc. Hope this helps
