hi guys

rite heres the prob please help if you can

car starts fine but missfires on boost and somtimes cuts out coming off of boost then when it get hot it wont start untill its cold again, by the look of the plugs it over fueling so i thought it might be the cold start valve so i disconected the fuel line to it and blanked it off but theres no change its still doing it also when it get hot it will miss and judder all through the revs

thanks in advance

 

sounds like leads,get some ford motorsport leads with motorcraft plugs should sort the problem

 

just put new plugs, leads, dizzy cap, and rotor arm on it

 

misses on boost, check all the boost pipes are on tight sounds like a boost leak

mine did it once missed like a bastard on boost like nearly shot me through the windon turned out i'd left a pipe undone

 

checked all that i took the plugs out and there all black so i think its over fuelling
