Hey guys,
Recently rebuild my engine ( again ), only thing that bugs me is the idle on a cold startup.
Idles good for about 2 seconds ( at 1200-1300 rpm ) and then drops to 500rpm and really lumpy.
Cold start injector has been disconnected for years and always started at the turn of the key ! ( edit : not the case , was with leaking injectors, different now ! )
Now i have to keep the revs up ( about 1500rpm) and hold it for about 10 seconds ( still lumpy while revved )and then it runs like normal at about 950 rpm.
Brake pedal is also hard when left for a few hours , any idea if that's part of my problem?
Also thought it might be leaking injectors but not sure about it ( renewed 2 years ago )

Cheers !
