Hi ,

problem I got is that above 4000 RPM the car cut outs if I keep pushing it climbs to 4500 but no power.

RPM meter stays stable ( no jumping ) and cold start runs 1200 RPM then to 900 RPM.

When hot I need to help starting with the gaspedal otherwise she doesnot start.

Sparkplugs are brown so no overfuelling

Car is 3 dr 1986 cosworth.

gasoline pressure 3 bar measured
turbo pressure ( from what I read on the dash ) around 0,7 bar
ignition cables are changed for MSD motorsport ones
new rotor
new distributor
new sparkplugs ford motorcarft 902 PP gapped 1 mm
phase sensor wiring was broken solderied soem new wired onto it.
new fuel pump last year
new fuel filter last year
new exhaust last year

running out of ideas here almost got a new car
