Misfire when cold

Post by vance5868 » Thu Jun 29, 2006 11:34 pm

When cold my bongo (diesel) misfires and cough,s on tickover , but clears when warm . Could it be a problem with the injecters ? Thanks

Depends when you had it serviced last, it could just be simply dirty plugs, seems a common complaint, rough start then smooth when warm, is there smoke when you start from cold, another sign of dirty plugs. I am sure someone will, hopefully also suggest other possibilities but look for the simple things first. Happy motoring.

Vance, I'm not being sarcastic, but are you waiting until the glowplug light on the dashboard goes out before starting the engine? Shakey

Yes mate , i understand what your saying but lasts for a mile or so when i get to junctions. Its not a constant missfire but a random one one every second or so ?

Well I would definitely start with the plugs, mine was similar and new plugs solved it, got to be worth a go. Happy motoring.

Glow plugs don't 'glow' for a mile! If you don't fire up within about 30 seconds of the light going out they will be cold again!
