Hi,
2-3 weeks ago my ST205 start running too rich,can smell fuel from the back. light throttle looks fine,just a little bit smell(fuel) from the back big boost get clouds of black smoke more than normal,not just more than normal,before that there is no any smoke or smells on big boost - my car is only 90000 km and is in perfect condition,engine is like new,turbo is like new,no any smoke on big boost until this problem? the car is standard running gear ... no mods,only downpipe,but fited along time ago. no ECU error codes,just old one storage in ECU 54 - low intercooler level,i have been changing pump bearings last summer,after this no problems with thah. check all vacuums - looks ok check o2 sensor - looks ok new spark plugs and leads - no leaks please help thanks in advance This post has been edited by EdinR-DrugB: Apr 7, 2015 - 11:52 PM |

yes the big cloud black smoke behind me is on 1st gear on big boost!on 2nd,3,4,5 clouds are smaller!
something strange happen ... there is no error codes on the dashboard but just run diagnostic on the car and comes two errors ... code 21- O2 sensor and code 00084 - don't know what is this!?when we start the car and let it idle code 21 showed LEAN and after 2 min. showed RICH!? probably the O2 sensor is lazy or something like this!? so i thing i have to change O2 sensor!?? or you have any other proposals!?? thanks in advance This post has been edited by EdinR-DrugB: Mar 21, 2015 - 9:42 AM |
