engine misfire

[music maniac]

hi all im new on here and my trusty 206 has been trusty untill recently, it was misfiring at turnover and wouldnt start, AA dont know wats wrong with it so took it to garage where i had map sensor replaced as it had gone, also had 4 new injectors as all 4 had managed to go at once and this made it work (for a day) but the next day i tried starting it and it has gone back to misfiring and the engine is flooded from the injectors filling the engine up,
can someone please help this is the only way of getting around and i still like my 206 and dnt want to let it go just yet

Welcome to the forum. I assume it's a petrol rather than diesel.
Normally I'd be looking at coil pack and spark plugs first off.
If not them I'd suspect contaminated fuel, water in fuel tank.
However, if you have had repairs carried out that cured it temporarily then I'd really suspect contaminated fuel. Do you have a habit of running about with the petrol tank less than half full? Do you use supermarket petrol?
Don't you think it too much of a coincidence for all 4 injectors to have failed at the same time?
