Desperate for help!!!!
 

Hi I am hoping someone will know whats wrong with my car it is a 2.5 auto v70 2000 reg non turbo, a few months it started behaving strangely it was like misfiring and the engine management light just flashed but didn't stay on we replaced two of the coils and ir solved the problem, then two months ago it came to a sudden stop on a A road while towing our caravan!! it turned out to be the alternator so £300 later it was fixed and ran fine then last week it just suddenly stalled but restarted straightaway it got worse over a few days some days it was intermittent but now its all the time it starts then drops revs then they go up again and then dies, I have bypassed the fuel pump relay and it still did it I have cleaned the ets also when it first started doing it the ets light did flash on and off but never stayed on, no engine management light is on so no codes are showing had it read twice, the only lights that stay on are the overdrive light and battery light has anyone got any ideas????????
