Mazda Bravo Smokey and Rough on Start up ?????

Hi All,

Agree to the Glow Plugs. Own a 2005 Bravo 2500 (2.5 ltr) Diesel and replaced the glow plugs a couple of times (over a period of time) and problem solved.

Diesel Mechanic recommend that if you have this problem in winter to turn IGN on/off a couple of times is a temporary measure and it works.

Cheers P&J.

Saw a similar model doing something similar last year so we replaced the glow plugs. That seemed to improve it but after another few weeks it was similar so sent it off to a diesel specialist who told us the head was cracked in an exhaust port. He said it was becoming a bit common in that model when they got up to around 150k. I think it ended up costing the owner a couple of grand to replace it. It did not use coolant at the time and the main symptoms were rough running start and soot. Hope it's not your problem but just a heads up for you. Bob.

Yes, black smoke is usually over fueling. White smoke is unburned fuel and has a particularly nasty smell.
