Backfiring is a symptom of fuel starvation or the timing being out. In this case it is probably fuel starvation (or a very weak mixture) as you say it happens when the engine is cold. The fuel mixture would normally be richer when the engine is cold, like having the choke on. Not sure if it is an engine management problem or...........have you tried cleaning the injectors ????

check the plugs lead. Do i have to replace the leads or can i fix them? does the replacement means the coils too? are they expensive?

You cant repair the leads, they have to be replaced. Are you getting oil in the plug wells? This seems to be a common 155 problem caused by a leaking gasket.
