87 mk1 gti, 1.8 8v.
just replaced the fuel pump and cleaned out the lines, and all was good.
on the first run the engine would stall if you braked sharply, but that seems to have stoped now, but last night i went for a long drive and on the way out it was all stuttery and felt and sounded like it was misfiring between 2500 and 4000rpm
on the way back it was worse and was stuttering right throughout the rev range. i've done the plugs, dizzy cap and rotor arm recently, anything else i should be checking?
