Quadrajet moan
Newly rebuilt original Q-Jet on my 400ci 1977 Pontiac Grand Prix. Taken during an 1100km/700mi road trip here in New Zealand. It used to stumble when cold and surge/hestitate at higher revs. These are gone now :-) Car is all stock including EGR etc. No modifications at all apart from removal of catalytic converter.
