Hi guys, need some pointers. Have a 53 TD4auto, she starts and runs perfectly then without warning the mil light comes on and the throttle drops to tickover after 5 seconds ish she revs up and away she goes as normal, the light goes off and she is fine. It could go a mile or 30miles before it happens. The under wheel arch pump and filter have been renewed and she goes well until this intermittent fault happens then fine 5 secs later, anybody any ideas? Second can anyone confirm, is the in line fuel pump under the arch the only one or is there a pump in the tank as well, seems strange to have 2 pumps up to the hp inj pump but the more i read some say 1 tank 1 inline and some say up to 53 tank after 53 inline, help me please,lol. Thanks
