I have a weird problem I haven't been able to nail down. If I drive my 79 E12 w/3.5, lets say second gear 1700 rpm though the neighborhood, it "trailerhitches". If I give it some accelerator pedal it goes just great. Maybe a Lean Surge condition.
I've checked:
Fuel pressure and delivery
AFM door movement
Throttle body Adjustment
2 different distro's
Vacuum(for advance, fuel regulator, and general manifold)
One thing I did notice, on the cold start fuel line that it was pulsating. Any ideas on why it would pulsate? I do have a Porsche adjustable regulator inline with the stock regulator(set at 33PSI)...
Ideas?
TIA
