1996 Volvo 850
When I first start my Volvo 850 a puff of black smoke will be emitted from exhaust. After the car starts it vanishes. I recently had my annual emissions check and have noe issues. it passed with flying colors. I have no CEL light, all maintenace completed including new battery, plugs, C&R, MAF and fuel filter. I have cleaned the TB and IAC as well. Car runs great with the exception of intermittant start problems where the engine takes 6-7 cranks to turn over, other times it starts no problem. But I am curious bout the black smoke at start up for a couple of seconds. Any ideas?
