Hi there for the last month I've been working on my car getting it all sorted I had to remove the turbo and manifold to change the radiator while I was there I got a mechanic in to change my Cambelt and water pump that's that now I've built it all back up I took it out put my foot down and it was chugging on off so I called mechanic back out to check timing was alright he looked over it said It was running fine so when I came home I took her out to get some petrol everything seemed fine when suddenly she cut out at the lights so started her back up revs kept dropping so held some revs on pulled off changed to second and there was a bang out the back and she cut out and wouldent start again got towed home left her to settle for a while turned her over she started give her some revs but then it seamed as if the revs wasent registering and she cut out again any ideas I got told the injectors needed cleaning so put some red ex cleaner in seems as if there's no combustion or there blocked up
