Hi everyone! Just bought a 2001 focus 1.6 zetec on saturday. quite pleased with it in general but one thing is niggling me..... when i got it on the motorway at first , it choked and lost pretty much all power under heavy load ( booting it through 70mph in 4th ) , exhaust backfiring , dropped away down to 5 mphh , putting the pedal down made it choke more and lose revs!
pulled over , engine off and back on and it got me home ok... thought maybe dirty fuel ? put redex through , filled the tank and revved the life out of it for a few mins and it seemed to clear and hasnt done it again . the only thing now is that theres a strong smell of petrol around the car and coming through the vents and the fuel economy doesnt seem quite right ( greedy! ) . Theres no leaking onto the road / pavement or obvious fuel spillage elsewhere.
On further investigation the car looks like its had a new coil pack ,new plugs , new leads and a new fuel pump. now im getting worried , you dont change all those parts unless your trying to clear a problem ?

ideas ?
