Car Forum / GMC Cars / February 2006smoke on a cold start
I have a 98 Grand Am with 3100 v6, everytime I start it after sitting overnight, black smoke comes out for a couple seconds when it starts, this car has had the engine replaced. Check for fuel in the vacuum hose to the fuel press regulator if so the reg is bad. >I have a 98 Grand Am with 3100 v6, everytime I start it after sitting >overnight, black smoke comes out for a couple seconds when it starts, this >car has had the engine replaced. would this also cause it to have poor pick up from a dead start?
