I submit to your superior wisdom, intellect and breeding, the following drive-ability concern:
The car:
'87 245 / M47 / B21FT swap. 740 turbo box, diverter valve routed back to intake, 3.0 bar regulator, breakerless distributor, LH2.2, orange tops.
The condition:
Generally runs great. 8 psi max. On occasion, in high-gear, at highway speeds, a light tip into the throttle yields a momentary engine "cut out." Like the fuel or ignition has been momentarily switched off, then on. It never feels like it's going to stall. But it is quite apparent to the occupants that there was a "hiccup." It's been happening for about six months now. This is a fairly repeatable condition. It does not occur under heavy throttle.
Thoughts, ideas?
