Chevrolet Captiva 2013 2.4litre ecotec 97500 miles
I have a 2013 capiva 2.4lt ecotec. 65litre tank and i only get 350km on a full tank. Ive removed the cat with a straight pipe, cleaned off the 2 O2 oxygen sensors, the maf sensor cleaned, added injector cleaner to fuel, and replaced both intake and exhaust solenoids and still blowing black smoke, black soot spots on my tail gate, a little rough idle but not much, its still burning up too much fuel, leads me to think its the injectors over fueling?
