hello there
my mk4 fiesta with a puma 1.7 conversion is winding mee right up so need your help

done the conversion and it doesnt run right dam thing so going to change lamda as the solus picked up that the lamda was over heated or under heated and it picked up that the cam time was too advandanced so retimed it all after the mot and it ran better it runs well till 3k then it kangarooosss like a bitch till it gets to 4k then its fine but its well down on power even after 4k and it also said that the vct solinoid could be not working right so will change lamda and get a proper auto electrian to do the wiring for the lamda extention

ive now got the new lamda and it still runs shit and when me and da retimed it today put the crank at tdc and the exhaust cam was in the correct place but the inlet cam was retarded so relined it all up correctly and then when you turn the engine over by the crank and the cambelt book says u get the crank back to tdc but the inlet cam has retarded again as when you first move the crank the exhaust cam will turn but not the inlet one and thn it will turn so any help please????????
