Well my car is finished but still at the mechanics, it turns on right away and runs smoothly and sounds B E A utifully, but them when it warms up the car starts to run rich and black smoke poors out of the exhaust. WTF is goin on, this is very bad and i dont know what to do about it. If you have any suggestions please let me know what to do. Oh and by the way the exhaust sounds like its a effin ferrari its sounds SOOOOO good i wasnt expecting that at all.

 

Well i just talked to some people at UltimateZ and Z1 and what they told me is to do a boost leak test, i really dont think that may be the problem and the guy at UltimateZ said that its the cold temperature sensor or something i couldnt hear him clearly he said to check the connector, i was thinking it might be a sensor problem also because when its cold its perfectly fine but as soon as the engine starts to warm up it runs rich and then the black smoke comes.

 

My first thought was temp sensor too. When you start up cold, it's set to run rich.
One other important thing to check is your coolant level. if it's low the warm coolant doesn't touch the sensor. Did you cycle your heater controls as you're filling it?

 

I dont believe that i did, hopefully its a problem with the temp sensor but i'm gonna try the coolent thing.

 

Well checked the temp sensor and thats fine, my mechanic drained coolent and filled it again. Hmm its still doing it, maybe i'll check over all of the wiring.

 

Well through many tests the mechanic has told me its a problem with the ECU thats my luck. He's not sure exactly whats wrong but he said hes gonna do a ping test, does any one have any ideas???? If u had something similar please let me know cause i REALLY wanna get my car back! i miss her
